Can a singly bonded CH2 group be classified as an alkyl or an alkane group? It's not the vinyl.

Thanks!

For some context Im trying to name all the groups of EDTA, there's some carboxylic acids and amines and some CH2 but idk what to call those lol

I think this site may explain it better than I can. Apparently it can be used one of three ways. In the sense of your question I believe methylene bridge is the correct usage. But see the other uses at this Wikipedia site.

A singly bonded CH2 group can be classified as an alkyl group. An alkyl group is a type of functional group that consists of a carbon atom bonded to hydrogen atoms and other carbon atoms through single covalent bonds.

To determine whether a CH2 group is a part of an alkane or an alkyl group, we need to consider its position within a molecule.

If the CH2 group is located as a substituent branch on a larger carbon chain, it is classified as an alkyl group. Alkyl groups are commonly found as substituents in larger organic compounds.

On the other hand, if the CH2 group is the main chain and there are no other functional groups present, then it is classified as an alkane. Alkanes are hydrocarbons that contain only carbon-carbon single bonds and are usually represented by the general formula CnH2n+2.

In summary, a singly bonded CH2 group is typically classified as an alkyl group, unless it is the main chain with no other functional groups, in which case it would be classified as an alkane.
