Butyl groups

WebButyl group: (1) Any saturated, acyclic alkyl group consisting of four carbon atoms, derived from butane or 2-methyl propane. Butyl Alcohols The butyl groups are shown in red 1-Butanol WebSo let’s consider the simplest example, and it is butane or butyl (alkyl group). Butane has four carbon and thus two possible structures. These are the so-called structural isomers. One is the 4-carbon straight chain which is call n-butane (“n” like normal), and the other is the 3-carbon chain with a methyl group on C2. It is ...

WebDec 11, 2024 · The tert-butyl group is bonded to three carbons from methyl groups, so this gives another $\ce{C, C, C}$ making it a tie again. If we look at the next set of atoms, the tert-butyl group has methyl groups so it's $\ce{H, H, H}$, giving it the lowest priority.
