Here it says to provide parent chain names for each compound. In A, we have two functional groups present. We have an amine here and then we have an alcohol. Remember, the priority when it comes to functional groups has alcohols having higher priority than amines. Because of that, the parent chain is the one that's going to include the alcohol. And if we just name the alcohol within a vacuum, meaning we're not paying attention to the amine portion, what would the alcohol chain be called? Well, we'd start numbering from the end closest to the OH, so 1, 2, 3, 4, 5, 6, 7. The alcohol is on carbon number 1, so that'd be 1, and then 7 carbons is hept, and then it's an alcohol, so heptanol.

For the next one, we have a carboxylic acid group here and then we have a ketone group here. Remember, carboxylic acids reign supreme. They are the highest priority functional group. So, we're going to pay attention to that. So, if we're just looking at the carboxylic acid part and ignoring the ketone because we're just concerned with the parent chain, what would it be called? So we would say it'd be 1, 2, 3, 4. Four carbons here would be butanoic acid. Now we have a methyl group attached, we have a ketone attached. They also be incorporated into the name as well. But for right now, we're just concerned with what the parent chain would be. So again, remember, the highest priority functional group forms the parent chain name. Everything else will be a substituent.
