 What about this one, if I write down this NH3 plus and NH2, NH3 plus and NH2, NH4 plus and NH2. No, this bond means there is a molecule attached with it, that's why it is NH3 plus 6, open bond means there will be a molecule attached, yes, right, so obviously this nitrogen attached 4 bonds, okay, when you write this, it means this nitrogen attached with this 3 hydrogen and one more bond this side with the molecule, okay, what about this one, NH3 plus, NH3 plus positive charges, it's a drag model, right, so NH3 plus will be, it will have more minus IC, what about this one, if I write down FOH and NH2, sorry, so there will be more, what about this one, chlorine, oxygen and nitrogen, we will compare, so chlorine is more electronegative, nitrogen is more electronegative, okay, SH and CL, SH and CL, chlorine is more electronegative, order will be this, okay, one more comparison, see triple bond and CH double bond, CH, sorry, CH double bond, NH or CH2 also you can write, or we can write CH2, NH2, which one, so why is there no difference, because you said only the sigma thing takes 4 bonds, so if there are more bonds, it's not like there is more bond, the first one is greater than, the first one more than sigma bond, why first one, because there are no hydrolytes, no hydrolytes and this is SP hydrolytes, so its electronegative will be maximum out of the things, so first of all we have to see that the molecule attached is this carbon, this carbon and this carbon, okay, so SP2 and this is SP3, which one is most electronegative, SP, why SP, for 50% S-director, right, so more electronegative drawing nature, okay, so order will be this, okay, C double bond OH and C double bond OSL, C double bond OH, C double bond OSL, tell us what it is, is it OH, why OH, so because over here both of them are pulling it, so lesser, which one is pulling, so it is only difference here, so in that one oxygen and chlorine are both, no but it's different things, so these two are very different here, so what is the difference in these two, here hydrogen and hydrogen, this is the difference, C double bond OH is attached to the molecule this side and here we attach the molecule same, so the bonding is same, difference is what, here hydrolytes, hydrolytes are the electronegative, see if we draw the electron, it means this guy as a whole, what will be the electron withdrawing nature, when we draw the electron this carbon is likely more electronegative in this concept, carbon, hydrogen, we don't consider electronegative difference, correct, so this is the thing, I have pulled it from here, it will pull from you, it will pull from you, it will be electronegative, okay, I took it from you, you took it from me, it will be electronegative, so this will take the electron, so what will it do, it will say I will get the electron, this molecule will get the electron, so its electronegativity, we can talk more than this but technically it is not correct, say that its electronegative is more, because both carbons are sp2, sp2 hybridization, okay, so order of minus sign will be more for this, so what do I have to see, I mean what is the difference between the molecule and the dash, based on that difference we need to check plus sign minus sign, so basically only hybridization and electronegativity, electronegativity is better, okay, so hybridization is one of the factor, because SKC have low electronegative nature, we find out that, we can, we are including electronegative nature of this carbon with the help of hybridization, okay, that is the thing, similarly one more example you see, if I write down this molecule as double bond OH, and double bond OH here, as double bond OH, what am I speaking about, first one, because here there is no difference, one extra oxygen will have, this will also pull, so if you look at hybridization, no, no, no, no, no, hybridization will check once we have this molecule, see the nature of the molecule is same here, here it is entirely different molecule, it has three oxygen, so overall its electron withdrawing itself, right, so similarly CF3, CCL3, CBR3 and CI3, what happens? CF3 is maximum, again fluorine is most electronegativity, right, logically you can do this kind of thing, okay, but there is an order of minus I effect, that order will write down, okay, but in the exam if you get this kind of molecules, okay, you know the nature of these molecules is minus I, and which one has more minus I effect, whatever that you can compare this way, okay, but you should know this order actually, you should know, you should have the idea of which one has more electron withdrawing nature or minus I nature, okay, so this write down this order as it is, NF3 plus is the most electron withdrawing group, NF3 plus is the electron withdrawing nature maximum head, and then we have NR3 plus NH3 plus, so what's the R? R is alkyl group, I will come to that, just see the order write down may I always tell you, NO2, cyanide, SO3H, C double bond OOH, chlorine, chlorine, then bromine, then iodine, C double bond OOR, OR, OH, C triple bond CH, then we have a phenyl group, phenyl group you know what is phenyl group, benzene ring say a hydrogen, okay, when benzene ring is attached with the group, it is phenyl group, phenyl group then we have alkene, CH double bond CH2, and then we have hydrogen, okay, you can remember the whole thing, but the order is important here that you must remember, say this one is important, alkyne sp hybridized carbon is more electronegative than phenyl group, which is more electronegative than alkyne group, means alkyne or alkyne can each one be alkyne this one is important, okay, this way question of your exam, okay, you order you must remember, R group this R is alkyne group, what is alkyne group, alkyne say if you remove one hydrogen it becomes alkyne, like methane, methyl is the alkyne group, okay, ethane, ethyl, butane, butane, propane, propyl, ethyl, okay, so in general alkyne and methyl are organic chemistry, okay, R is the alkyne group, and alkyne group are generally electron releasing group, this one are electron withdrawing, but alkyne groups are electron releasing, electron release ok, now one thing you see NH3 plus NH3 plus NR3 plus, which one of this has more minus You said... Nr3 Nr3, why? I told you today, yes. So, you still get R... R... Donate like... Yes, donate to electron. So, that means that N will have a... Less density of positive charge. Yes. See, what happened here? I got logically... They do not know the order, okay? All logically, if you think. Like I said, This alkyne groups are electron... Deleasing. Okay? This alkyne group release electron. Okay? And here, this won't release electron. So, where we have more positive... More density of positive charge? First one. Okay? Yes. If this electron is released, then this question will decrease. So, here we have more density of... Positive charge. If you have more density of positive charge, then this should withdraw more electron. So, logically, if you think, the order should be this. So, if you do not know this, the exam will be wrong. Okay? This is the first magic of organic chemistry. Okay? You should know this thing that Nr3 plus has more minus high effect. Okay? Q has more logic than... What is this Q? But, we have to think about exceptions. To understand, we'll have a logic here. And what is the logic here? Because alkyne group's P orbital and its P orbital will be involved. Okay? P P orbital, P P and P P orbital will be involved. Okay? It won't be S. It won't be P. What happens here? Its S and its P will be involved. Okay? Its S will be involved. So, overall, here, S corrected will be less. The available S corrected will be less. But here, since only P is involved, so here, the available S corrected will be comparatively more. If you read a lot of higher books, you'll get something logical. I don't know much about this. No, I saw that it is being involved and how is the S corrected more? More. I'm saying overall S corrected. Overall S corrected. For the molecule, here, since P P is involved, overall S corrected of this molecule is more because this will also affect the electron withdrawal in nature of nitrogen. Okay? Even in CO, H and CO, because, like, if I have R, then it's giving power to oxygen. Correct, correct. So, oxygen will pull less from carbon. Correct, correct, correct. So, then that makes sense. That makes sense. Yeah, so then that makes sense. But that is, see, you cannot apply this here because this carbon is attached with the molecule. Yes, that's correct. But here, it is critical. Yes, yes. Here, it is critical. Okay? So, here the order of Nr3 plus is more than to that of Nr3 plus because it has more available S corrected. Okay? Here, logic, D, R, and P also do. But I'll suggest, you give it an exception. Even, yeah. Even if you take the same logic, we'll have this order also of O, H, and OR. O, H, and OR will also be compared. So, this is the electron releasing it. Okay? So, what will be the electron density here? This electron with drawing nature will come over. Because this is giving electron. So, this electron with drawing nature of oxygen will be less than this in comparison. But actually, the order of this. Okay? With the same logic. Because it is the available S character. Okay? So, this is the example you must take. Okay? Write it down. But note, make it. Next slide down. Plus i group. Plus i group. These are the electron with drawing group. These are the electron releasing. Not behind, sorry. Electron releasing group. All alkyne groups are electron releasing group. Electron releasing group. If you take the isotopes of hydrogen like CT3, CT3, and CH3. Tritium, deuterium, and proteam. Okay? Hydrogen we have here. So, for this the order for CT3 is more than that of CT3 and CH3. Why? That's the logic. But again, I'll suggest you to memorize this. Okay? So, I'll tell you what I'll tell you. Okay? So, in this you write down the bond length of CH is maximum and CT is minimum. We'll use this bond length thing in hyper conjugation. Okay? Just you write down this order. Bond length of CH is maximum and CT is minimum. Okay? So, which bond is the strongest here? CH or CT? CT. Bond length maximum as CHka. So, bond strength minimum of CHka. Bond strength of CT is maximum. Okay? In this you write down, as bond length increases, tendency to lose electron decreases. Write down, due to high mass number, due to high mass number, the vibration of bond pair of electron is less and hence the bond length decreases. Right? So, when mass number increases, the bond pair of electron, its vibrating tendency is very less because of the higher mass of the isotope. Okay? So, bond vibration is less, hence bond length decreases. Bond length decreases. So, electron releasing tendency will be less. Okay? So, this order you must remember. Next one you see, ethyl, if you have, if the molecular mass increases, suppose we have ethyl in this one. This is ethyl CH2, CH3, propyl CH2, CH2, CH3. So, if you compare the electron releasing tendency of these alkyl group, okay, as the carbon atom increases, the number of carbon atom increases, or mass increases, electron releasing tendency also increases. Okay? Which one of these has maximum electron releasing tendency? CH3. The last one. The last one has maximum. Okay? Because this three alkyl group releases electron. Okay? So, overall this carbon can release more electron. Okay? This one is maximum. Here we have only two such groups. Here we have only one, and here we will not have any. Okay? So, this one we have relative. We will just compare the given molecules in that question. Okay? H2O is not an acid. Okay? H2O has acidic behavior. But H2O is more acidic than methanol. CH3 always. So, organic chemistry, whenever you have the, we have to do the comparison of acidic spin. So, emotional. Okay? Okay? Whatever given molecule there, we have to take that decision. Okay? Based on the, you know, logic and whatever concepts we are studying for that. Okay? So, the point I am trying to make is what? The acidic strength, basic strength, stability, all these things are always relative. Okay? Whatever given molecule there, we have to do the comparison. Okay? Next I will write down, so two different effects we have done.
