 Amide, amide is C double bond O NH2, this is amide, we will start coming from this carbon atom, first question is this and the subjects for this is amide only, for example if you have CS3, C double bond O NH2, 2 carbon atom, name of this compound is ethylamide, okay. Sir, those are substituted amides, right? Yes, so when substituted amide is there, we will write N-methyl, for this one we will write N-methyl for this, N-methyl in 1, 2, 3. Suppose if you substitute one methyl group here, it becomes N-methyl ethylamide, right. N-methyl means the methyl group is attached with nitrogen atom, N means capital N. So if you have this CS3, C double bond O, N-et, N-et, so it is N, N-ethyl ethylamide. It will be N-ethyl ethylamide, right. N-nethyl ethylamide. N-nethyl ethylamide. N-nethyl ethylamide. N-nethyl ethylamide. N-nethyl ethylamide. What about this one? N-nethyl ethylamide. 2 N-mitra triodotamide. N-mitra triodotamide. N-mitra triodotamide. N-mitra triodotamide. N-mitra triodotamide. N-mitra triodotamide. Why N-mitra triodotamide? What happened? Yeah, of course. N-t, note, I'm not like N that's number. Sorry. Oh no, I was talking about the next one. It's correct. It's correct. It's correct. Correct? Correct. The second one. I made a mistake here. We should write this first to a triodotamide. It is triodotamide. Here we have different things. It is triodotamide first. Alphabetically we'll write N-mitra triodotamide. And then N-mitra triodotamide. So from there, do we take the N of the N-mitra triodotamide? No, N-mitra triodotamide. This only means that this methyl is attached with nitrogen. Okay? Whatever comes first alphabetically, it will write. So here what we'll write? flashes What about this one? N promo build 3 inamai. Isn't the end which gone? No. N promo build 3 inamai. This one we have N promo and 1, 2, 3 clodo. So it is N promo, 3 clodo, 2, 10 inamai. But here we will write promo first, so 3 promo and clodo, cute inamai. Amines are the alkyl derivative of ammonia. We can have aryl derivative also generally it is alkyl. Like for example ammonia is NH3 and when you replace one of the hydrogen atom with one alkyl group it becomes RNS2. This is 1 degree amine. When nitrogen attachment only one alkyl group it is 1 degree amine. When one more hydrogen you replace it is 2 degree amine, secondary amine or when you replace all the hydrogen atom it becomes 3 degree or tertiary amine. Subfix is also amine for this. Amines are amines. Amines are 3 double bond of NNS. Amines are this. It is not alkyl derivative. Subfix is amine. Suppose we have this CS3NH2, CS3 CS2NH2. Carbon atom is number one. Sir do we also give a number like amines? No, that is the problem. Sir but then you could have multiple times of compounds right depending on where I am at. You have one amine not required for that. Everything is here. Everything is here but I am trying many things right now. It is not there. Because at that point it is here sir. 3 times amines. We have to give the number to the carbon atom. Where NNS2 is? Sir it would be like 3 amines. What about bromide? 2 bromide. 2 bromide. 2 bromide. What is the position of NNS2? We have to mention. How do we say? This one is methanamide. Yes sir. It is not too high. This methanamide. This one is ketanamide. What is amine? Now in this one, numbering if you do 1, 2, 3, 4 and 5. So it is 2 bromide. Penche. 3 amine. Like this. Third position? 3 amine. This one? Butte 2 amine. Both one is butte 2 amines. So sir when there is a number we do not write the an. Only ketanamide. Not required. If it is double bond is there that position you have to mention. Sir like how do you mention it? Let's say it is a double bond. I will write it on example. NNS2. And suppose we have a double bond here. Or here we have a double bond. So it is 1, 2, 3, 4. It is butte 1 in 4 amine. Butte 1 in 4 amine. Sorry. Butte 1 in 4 amine. Here also you can write penche 3 amine. Penche 3 amine. Butte 2 amine. What is the name of this one? Only one carbonate. N, N time is like methanamide. N, N. Any number is equal. Suppose if you have CS2, CS2 here. The longest chain will be this. So we take the longest chain. Here all are equal. Here all are same. But if you have this. Then we are bound to take this. Sir but what if there was like a pen. A profile chain and a high school profile chain. Longest chain. Write the profile. Here we have 2 carbonate. Here we have 3 carbonate. N methyl and ethyl. First you write N ethyl and ethyl. Here we have 3 carbonate. Longest chain is 3 carbonate. Here we have only 2. Only one. This is the longest chain. N ethyl and ethyl propane to amine. Longest chain ethyl to amine. Longest chain. Longest chain ethyl to amine. So what if you see these 2 carbonate. What is a carbonate? This is not a carbonate. 1, 2 and 3. What if you see the carbonate. 1, 2 and this guy. You cannot start this between us. Let's start all this with W carbon. Right. You can start from this carbon. Then we have 2 carbonate. Only one carbonate. 1, 2, 3 carbonate. So what if those 2 carbonate were born then. Only you. No sir you can move on hydrogen like from hydrogen. You can do that. How do we name that? Exactly. It becomes tessa compound. As a compound and then 1, 2 and ethyl as a cyclotutate. Do we have any cutting? I see that. I think that is what it is. Yes. Okay understood this.
