Question

Predict the product B.
$C{H}_3-N{H}_2+NaN{O}_2+2HX\underset{H_{2}O}{\overset{\left(HONO\right)}{\to }}\underset{\text{Highly unstable}}{A}\stackrel{H_{2}O}{\to }B$

• A. $C{H}_{3}X$
• B. $C{H}_{3}N{O}_2$
• C. $C{H}_{3}OH$
• D. None of the above

Answer 1

The correct option is C $C{H}_{3}OH$

Primary aliphatic amine on reacting with $NaN{O}_2$ in presence of acid (HX) it forms a highly unstable diazonium salt which on treating with water gives primary alcohol.


$C{H}_3-N{H}_2+NaN{O}_2+2HX\underset{H_{2}O}{\overset{\left(HONO\right)}{\to }}\underset{\text{Highly unstable}}{C{H}_3-N_2^{+}{X}^{-}}\stackrel{H_{2}O}{\to }C{H}_{3}OH$
