Assertion: When an ether containing a primary alkyl group and tertiary alkyl group is treated with hydrogen iodide, tertiary alkyl iodide is formed.
Reason: The reaction takes place via $S_N1$ mechanism, and the more stable tertiary carbocation is formed easily which combines with iodide ion to form tertiary alkyl iodide.
- aBoth Assertion and Reason are true, and Reason is the correct explanation for Assertion.
- bBoth Assertion and Reason are true, but Reason is not the correct explanation for Assertion.
- cAssertion is true and Reason is false.
- dBoth Assertion and Reason are false.

Correct option: a
Answer: (a) Both Assertion and Reason are true, and Reason is the correct explanation for Assertion.
When an ether with a tertiary alkyl group is cleaved by $\text{HI}$, reaction proceeds via an $S_N1$ mechanism forming a stable tertiary carbocation, yielding tertiary alkyl iodide.
