Vedclass · Answer

(D) The reaction of an ether with $HI$ proceeds via an $S_N1$ or $S_N2$ mechanism depending on the nature of the alkyl groups attached to the oxygen atom.In the given ether, $CH_3-CH_2-CH_2-O-C(CH_3)_2-CH_2-CH_3$, one alkyl group is a primary alkyl group ($n$-propyl) and the other is a tertiary alkyl group ($2$-methylbutan-$2$-yl).When an ether has a tertiary alkyl group, the reaction follows the $S_N1$ mechanism because the tertiary carbocation is highly stable.The oxygen atom is protonated by $HI$ to form an oxonium ion, which then undergoes cleavage to form the most stable carbocation.The tertiary carbocation, $CH_3-CH_2-C^+(CH_3)_2$, is formed, which then reacts with the iodide ion $(I^-)$ to form the tertiary alkyl iodide, $CH_3-CH_2-C(I)(CH_3)_2$.The remaining part forms the primary alcohol, $CH_3-CH_2-CH_2-OH$.Therefore, the major products are $CH_3-CH_2-CH_2-OH$ and $CH_3-CH_2-C(I)(CH_3)_2$.

Give the major products formed by heating $CH_3-CH_2-CH_2-O-C(CH_3)_2-CH_2-CH_3$ with $HI$.
