Draw the structure of each carboxylic acid or ester. a. pentanoic acid

Video transcript

Welcome back, everyone give the structure of the molecule with the name Hexon OIC acid. According to the name, we have a carboxylic acid in question. And carboxylic acids have a general form of R coo H that's the general form of a carboxylic acid. Essentially, we don't see any substituents in this name because this name has a form of alcaic acid and it essentially means that there are no subscriptions and no branching. Now, what we want to understand is that Alkan OIC acid, the first word of this name essentially allows us to understand how many carbon atoms we have. In our parent total. In this case, we have a Hexon OIC acid and we want to recall that hex A as a prefix means sex. So we have a total of six carbon atoms in the longest continuous chain. What we can do is first we will draw a carboxyl group. So our double bonded carbon hydroxyl oh And this is where we have to recall that carbon number one is always the one that is within the carboxyl group, the double bonded one. And therefore, if taxono acid and we are expected to have six carbons. We simply want to draw that alky group as a five member chain, which will give us a total of six. So we have our first carbon. Let's draw the second one, the third one, the fourth one, the fifth one and the sixth one. Let's double check. 12345 insects. That's Hexon OIC acid because it has a carboxyl group and a total of six carbon atoms in the longest consin carbon chain. Thank you for watching.
