Q. In the reaction: (CH₃)₂CH–CH₂–O–CH₂–CH₃ + HI —Heated→ Which of the following compounds will be formed?
A) (CH₃)₂CH–CH₃ + CH₃CH₂OH
B) (CH₃)₂CH–CH₂OH + CH₃CH₃
C) (CH₃)₂CH–CH₂OH + CH₃–CH₂–I
D) (CH₃)₂CH–CH₂–I + CH₃CH₂OH
Explanation
[Solution from source] With two primary alkyl groups, I⁻ attacks the less hindered carbon by SN2 after protonation of the ether oxygen. The ethyl carbon is less hindered than the isobutyl carbon, so the products are CH₃CH₂I and (CH₃)₂CHCH₂OH. Answer (3).
