Question

B(mix) $\xleftarrow[{2}]{\text{conc.HI}}CH_{3})_{2} C —O—CH_{3} \xrightarrow[{1}] { {\text{anhydrous HI}}}$A (mix)

• A. A and B are identical mixture of $CH_{3}I$ and $(CH_{3})_{3}C —OH$
• B. A and B are identical mixture of $CH_{3}OH $ and $(CH_{3})_{3} C—I$
• C. A is mixture of $CH_{3}I$ and $(CH_{3})_{3}C—OH$ B is a mixture of $CH_{3}OH$ and $(CH_{3})_{3}C—I$
• D. none of these

Answer 1

Answer: (C)

$(CH_{3})_{2}C—OCH_{3} \xrightarrow{{\text{Anhy.HI}} }CH_{3}I+(CH_{3})_{3}C—OH$
$(CH_{3})_{2}C —OCH_{3} \xrightarrow{{\text{Conc.HI}} }CH_{3}OH+(CH_{3})_{3}C—I$
