Question

HBr reacts with $$\mathrm{CH}{\phantom{A}}_2=\mathrm{CH}-\mathrm{OCH}{\phantom{A}}_3$$ under anhydrous conditions at room temperature to give ______.

पर्याय

• $$\mathrm{BrCH}{\phantom{A}}_2-\mathrm{CH}{\phantom{A}}_2-\mathrm{OCH}{\phantom{A}}_3$$

• $$\mathrm{H}{\phantom{A}}_3\mathrm{C}-\mathrm{CHBr}-\mathrm{OCH}{\phantom{A}}_3$$

• $$\mathrm{CH}{\phantom{A}}_3\mathrm{CHO}\mathrm{and}\mathrm{CH}{\phantom{A}}_3\mathrm{Br}$$

• $$\mathrm{BrCH}{\phantom{A}}_2\mathrm{CHO}\mathrm{and}\mathrm{CH}{\phantom{A}}_3\mathrm{OH}$$

Answer 1

HBr reacts with $$\mathrm{CH}{\phantom{A}}_2=\mathrm{CH}-\mathrm{OCH}{\phantom{A}}_3$$ under anhydrous conditions at room temperature to give $$\underset{―}{\mathrm{H}{\phantom{A}}_3\mathrm{C}-\mathrm{CHBr}-\mathrm{OCH}{\phantom{A}}_3}$$.

Explanation:

Methyl vinyl ether under anhydrous condition at room temperature undergoes addition reaction.

$$\begin{array}{c}\mathrm{CH}{\phantom{A}}_2=\mathrm{CH}-\mathrm{OCH}{\phantom{A}}_3\stackrel{\mathrm{HBr}}{\to }\mathrm{CH}{\phantom{A}}_3-\mathrm{CH}-\mathrm{O}-\mathrm{CH}{\phantom{A}}_3\\ \phantom{...................}|\\ \phantom{....................}\mathrm{Br}\end{array}$$
