Answer 1

Tert-butyl methyl ether on treatment with hydrogen iodide in cold gives tert-butyl iodide and methyl alcohol.

Explanation:

The reaction between tert-butyl methyl ether with hydrogen iodide:

\[\begin{array}{cc}
\ce{CH3}\phantom{..........................}\ce{CH3}\phantom{.....}\\
|\phantom{..............................}|\phantom{.......}\\
\ce{H3C - C - O - CH3 + HI -> H3C - C - I + CH3OH}\\
|\phantom{...............}\text{(cold)}\phantom{...........}|\phantom{.......}\\
\phantom{.....}\ce{\underset{Tert-butyl methyl ether}{CH3}}\phantom{}\text{Hydrogen iodine}\phantom{..}\ce{\underset{Tert-butyl iodide}{CH3}}\phantom{}\text{Methyl alcohol}\end{array}\]
