hey guys, was just wondering if you could help clear up a few facts with the naming of basic organic molecules (up to C10). When we refer to things such as alkenes, chloroalkanes, alkanols, carboxylic acids and amines, with the naming process, the main chain is always the longest one that contains the double bond/ or functional group. Is this right?

Yes, however if more than 2 functional groups present in an organic compound, name the longest carbon chain that contains higher priority functional group than the other first.

For reference.

The fundamental starting point is find the longest carbon chain then start adding side groups or functional groups. The real trick is to know which functional group to start counting from.
