Question

Predict the two most likely mechanisms which occur when 2-iodohexane is heated in ethanol.
Options
A SN2 and SN1
B E1 and E2
C SN2 and E2
D E1 and SN1
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

When 2-iodohexane is heated in ethanol (a polar protic solvent, weak nucleophile, weak base), it undergoes solvolysis via SN1 and elimination via E1. The weak nucleophile/base and formation of a carbocation intermediate favor both SN1 and E1.

Hint

What mechanisms are favored with a weak nucleophile and polar protic solvent?
