Q. The structure of isobutyl group in an organic compound is
A) (CH₃)₂CH–CH₂–
B) CH₃–CH(–)–CH₂–CH₃
C) CH₃–CH₂–CH₂–CH₂–
D) (CH₃)₃C–
Explanation
[Solution from source] Isobutyl is (CH₃)₂CH–CH₂–, attached through a CH₂ next to the branched carbon. CH₃–CH(–)–CH₂–CH₃ is sec-butyl, (CH₃)₃C– is tert-butyl and the straight chain is n-butyl. Answer (1).
