Welcome back everyone. It's another video which of the following functional groups are present in Cephalexin structure, select all that apply. We're given the structure on the screen and we have five options. Those are amide carboxylic acid alcohol. Er And I mean, so let's carefully look at the given structure. First of all, let's consider the presence of an aide. Well, an amide must have carbonel, so we must have carbonel ceo and then there must be NGEN directly attached to carbonel with some alkyl group. On the other side side of Carno Ngen can be attached to either carbon atoms or hydrogens. So we can clearly see that yes, we have amides. First of all, there is a cyclic amide con, right? And then we have another aide con we don't really worry if those are carbon atoms only or ni were hydrogen atoms bonded to carbon, right? As long as we have Carboni with Ngen directly attached. Well, that's basically an amide. So we can say that yes, we do have an amide. Now, carboxylic acid is very similar, we have carbonyl and then there is a bonded to carbonyl carbon with an alkyl group on the other side of carbonyl and we indeed have the carboxylic acid presence coo H right. And then there is carbon atom bonded to carbonyl. So carboxylic acid is also correct. Now, for the alcohol we simply want to have are bonded to oh we want to identify any oh present and we have none, right. So essentially there is no alcohol for the Esther, we simply want to have carbona with some coxie group and then we want to have an alkyl group. On the other side, we don't have that as well. We already have we Carbonis, those are amides and a carboxylic acid. So there is no ester. And finally, for an amine, we simply want to have nitrogen bonded to an alkyl group. Ngen can be bonded to hydrogens. For example, it can have two hydrogens or two alkyl groups. It depends, right, what type of mean we are looking for, it can be primary secondary or tertiary. So we can clearly see that there is actually an amino group. It is a primary amine NH two bonded to carbon. So we definitely have an amine in the structure and we can say that for this problem, the correct answer would be aide number one, carboxylic acid, number two and amine, which is number five. So 12 and five is the correct answer. Thank you for watching.
