The reaction follows the SN1 pathway due to the presence of a tertiary alkyl group.

1. CH3—C—O—CH3 + HI → CH3—C—O—H → CH3OH
2. CH3—CH—CH2—O—CH2—CH3 + HI → CH3—CH—CH2OH + CH3CH2I
3. CH3—C—CH3 + HI → CH3—C—I
4. CH3—C—CH3 (Highly stable)

Correct answer: CH3—C—CH3 + HI → CH3—C—I

Solution

The SN1 mechanism is favored by tertiary alkyl groups due to the stability of the carbocation intermediate. Option C involves a tertiary alkyl group, making it the correct choice.
