Vedclass · Answer

(A) When an ether contains a tertiary alkyl group,the reaction with hot concentrated $HI$ proceeds via the $S_N1$ mechanism. In the case of tert-butyl methyl ether $(CH_3-C(CH_3)_2-O-CH_3)$,the $C-O$ bond cleavage occurs such that the stable tertiary carbocation $(CH_3-C^+(CH_3)_2)$ is formed. This carbocation then reacts with $I^-$ to form tert-butyl iodide,while the methoxy group is protonated to form methyl alcohol $(CH_3OH)$. In contrast,for primary and secondary alkyl ethers,the reaction follows the $S_N2$ mechanism,where the nucleophile $I^-$ attacks the less sterically hindered carbon (the methyl group),resulting in the formation of methyl iodide $(CH_3I)$ and the corresponding alcohol.

Among the following ethers,which one will produce methyl alcohol on treatment with hot concentrated $HI$?
