Question

Compound $C_2{H}_{6}O$ has two isomers X and Y. On reaction with $HI$, X gives alkyl iodide and water while Y gives alkyl iodide and alcohol.Compounds X and Y are respectively :

• A. $C_2{H}_{5}O{C}_2{H}_{5}andC{H}_{3}O{C}_2{H}_5$
• B. $C{H}_{3}OC{H}_{3}and{C}_2{H}_{5}OC{H}_3$
• C. $C_2{H}_{5}OHandC{H}_{3}OC{H}_3$
• D. $C{H}_{3}OHandC{H}_{3}OC{H}_3$

Answer 1

Answer: (C)

$C_2{H}_{5}OHandC{H}_{3}OC{H}_3$

$\underset{\left(X\right)}{C_2{H}_{5}OH}+HI\to C_2{H}_{5}I+H_{2}O$
$C{H}_{3}O\underset{\left(Y\right)}{C}{H}_3+HI\to C{H}_{3}I+C{H}_{3}OH$
