 Right on hyperconjugation in carbocation, see carbocation again the condition is same we need sp3 hybridized alpha hydrogen CH2 plus correct. So, it is hyperconjugative structure is what again this sigma converts into pi this gives you H C H plus double bond CH2 intermediate is an alkene it is not in carbon ion here right. So, similarly we can brought two more structure with these two hydrogen. So, number of hyperconjugating structure is what here again we can write the same formula alpha hydrogen plus one. So, sir here is the function group this is a carbocation function it is not a carbocation here generally with respect to this this is the alpha hydrogen. If you have CH3 CH2 OH alcohol then also this is the alpha carbon here adjacent to the carbon which has the function group ok. Functional grouping you cannot say it is this one it is a carbocation intermediate and adjacent carbon of carbocation intermediate is also alpha carbon ok because carbocation is not a function. Sir in that alcohol should not the other see the alpha because the function group is OH right. Yes. So, the carbon next to it is the one that is directly wanted to OH correct. So, this is attached with OH this carbon if attached with this methyl group this methyl group and this methyl group. So, we will see the alpha carbon are all those carbon which attach to this carbon atom which has the function. So, this is not alpha carbon this is alpha this is alpha. So, it is always carbons attached to the carbon which contains this function. The carbon atom which contains the functional group adjacent to that carbon all those carbons are alpha carbon. So, in this case the number of alpha hydrogen is what 3 plus 3 minus 9 ok. So, I will see one thing here hyper conjugation also stabilize this carbocation ok this comes over here and this stabilizes. So, if you talk about the stability of this carbocation this CH 3 CH 3 CH 3 positive charge on this and then CH 3 CH 3 positive charge CH 3 CH 2 positive charge which one is more stable. See this is also electron is releasing it is giving electron to this positive charge carbon that is why this becomes neutral here and we know when the electron releasing group is there that stabilizes the carbocation correct ok. So, the hyper conjugation also stabilize carbocation correct. So, in this case the stability of carbocation if you compare which one is more stable first one why we can talk about what we can talk about plus i effect of 3 with high group here we have only 2 plus i effect here we have only 1 plus i effect. So, because of plus i effect also the stability of this is maximum and at the same time we can also talk about hyper conjugation number of alpha hydrogen is what here 9 3 plus 3 plus 3 9 number of alpha hydrogen 6 number of alpha hydrogen 3. So, more alpha hydrogen more hyper conjugative structure more will be the stability of hydrogen. Hyper conjugation we know dominates i effect. So, we can say it is also stabilize through hydrogen sorry hyper conjugation right i effect is also there but hyper conjugation is also there. Compare the stability of these 3 carbocation. This is 3 degree if you talk about i effect 3 degree 2 degree 1 degree order of stability is this right if you talk about hyper conjugation how many alpha hydrogen here 2 4 plus 3 7 number of alpha hydrogen here 2 plus 1 3 number of alpha hydrogen 1 alpha hydrogen more stable same thing. In this 2 what happens number of alpha hydrogen 2 number of alpha hydrogen S P 3 hybridized this is alpha carbon right. We are talking about stability of carbocation so with respect to this we will see. How many hydrogen we have here 1 2 3 1 double bond we already have you know there is no hydrogen present here. What which one is more stable than but the order is this. But it is resonance stabilizer see here we have hyper conjugation but here we have resonance. Resonance stabilizer is more than hyper conjugation that is why when you get the question you have to think about all the electronic effects. This is see we are talking about carbocation this is not in conjugation stability of carbocation here so we can it is possible but this is not in conjugation okay understood. See here this carbocation is in conjugation with this pi bond pi sigma positive charge but here it is positive charge sigma and sigma there is no conjugation here. Here we have no resonance positive form right but here we have hyper conjugation means we can say this carbocation is stabilized through hyper conjugation but this carbocation is stabilized through resonance resonance dominance hyper conjugation this one is more stable okay in this one which one is more stable. Second one. Second one. This one do we have hyper conjugation possible here possible what is the condition of hyper conjugation SP3 hybridized alpha hydrogen which is there this carbon is SP3 hybridized 2 hydrogen so number of alpha hydrogen is here 2 number of alpha hydrogen here again 2 right so hyper conjugation. Second one has resonance. Where is the resonance? It is changing. It is changing you can. There is no. You do have pi. See first of all hyper conjugation hyper conjugation so number of alpha hydrogen is same so hyper conjugation is surprised so both carbocation equally correct right. So hyper conjugation say we cannot decide this. Do we have resonance possible? No resonance is possible. You need a pi bond right. No pi bond. I will let me finish first. Hyper conjugation we cannot decide. Do we have resonance possible? No. Where is resonance? Do we have conjugation here pi, sigma, pi, sigma, pi. This is no pi bond. Okay. This is the thing. No pi bond. Where is the pi bond? You do double bond with CH2. Then CH has pi bond sir. Yeah. Yeah correct. You double bond with CH2. I am very emotional. There is no double bond sir. See there is no double bond. Correct. Resonance is not possible. Fine. Right. Now third. I effect to consider. Yes. I effect to we can consider. Here we have ethyl I effect. Here we have profile I effect. So which one has more I effect. Propile sign increases. I effect increases. So this one will be more stable. Shows more plus I than this ethyl group. So this step line this carbocation more order of step. Okay. So one by one you have to think. See order is this. Resonance is most effective than hyper conjugation than I. Okay. So subsequent residence you have to find out. If it is there fine. Then hyper conjugation then I effect. Yes sir. Sir what if there is like a lot of hyper conjugation versus a little bit less. No. So like. See versus though we cannot compare. But this is the order. If you have two different effect then residence always goes like this. Resonance always goes like this. Because largest group gives more electrons. Ethyl has more plus I than which high. Like that. Okay. So this group gives more plus I than this group. Enthusiasticity is this. Okay.
