Side chains chemistry
WebThe side chains are: an ethyl- at carbon 4, an ethyl- at carbon 8, and a butyl- at carbon 12. Note: the −O−CH 3 at carbon atom 15 is not a side chain, but it is a methoxy functional group. There are two ethyl- groups. They are combined to create, 4,8-diethyl. The side chains are grouped like this: 12-butyl-4,8-diethyl.
