Vedclass · Answer

(B) When dimethyl ether $(CH_3-O-CH_3)$ is heated with excess $HI$,the ether linkage is cleaved.In the first step,one $C-O$ bond breaks to form $CH_3I$ and $CH_3OH$.In the second step,the excess $HI$ reacts with the formed $CH_3OH$ to produce another molecule of $CH_3I$ and water $(H_2O)$.The overall reaction is: $CH_3-O-CH_3 + 2HI 	o 2CH_3I + H_2O$.
