Root Explanation

Isobutylene is formed from "iso-" (meaning equal or same) and "butylene" (from the root "butyric" which is derived from the Greek word "bous" meaning cow, referring to butyric acid found in butter). The term describes a specific type of butylene that has a branched structure, indicating its similarity to butylene but with a distinct arrangement.

Memory Tip

Think of 'iso-' meaning 'same' and 'butylene' relating to a type of compound — isobutylene is a similar but distinct form of butylene.
