Q. The major organic product in the reaction, CH₃–O–CH(CH₃)₂ + HI → Product is :
A) CH₃OH + (CH₃)₂CHI
B) ICH₂OCH(CH₃)₂
C) CH₃O–C(CH₃)₂I
D) CH₃I + (CH₃)₂CHOH
Explanation
[Solution from source] HI protonates the ether oxygen and I⁻ attacks by SN2 at the less hindered carbon, which is the methyl group. The products are CH₃I and isopropyl alcohol, (CH₃)₂CHOH. Attack at the secondary isopropyl carbon, giving CH₃OH and isopropyl iodide, is slower under these conditions. Answer (4).
