Vedclass · Answer

(A) The reaction of an ether with excess $HI$ involves the protonation of the ether oxygen followed by nucleophilic attack by $I^-$.$CH_{3}CH_{2}CH_{2}OC(CH_{3})_{3} + HI \rightarrow CH_{3}CH_{2}CH_{2}OH + (CH_{3})_{3}CI$.Since $HI$ is in excess,the alcohol formed $(CH_{3}CH_{2}CH_{2}OH)$ further reacts with $HI$ to form an alkyl iodide.$CH_{3}CH_{2}CH_{2}OH + HI \rightarrow CH_{3}CH_{2}CH_{2}I + H_{2}O$.The tertiary carbocation formed from the cleavage of the $C-O$ bond in the tert-butyl group is highly stable,leading to the formation of $(CH_{3})_{3}CI$.Thus,the final products are $CH_{3}CH_{2}CH_{2}I$ and $(CH_{3})_{3}CI$.

The major products $C$ and $D$ formed in the following reaction are:
$CH_{3}CH_{2}CH_{2}OC(CH_{3})_{3} \xrightarrow[\Delta]{\text{excess } HI} C + D$
