Q1 / 90 · JEE Main 2023 (12 Apr Shift 1) · Chemistry

The incorrect statement regarding the reaction given below is

A
The product ‘ $B$ ’ formed in the above reaction is $p$ -nitroso compound at low temperature
Correct answer
B
‘ $B$ ’ is $N$ -nitroso ammonium compound
C
The reaction occurs at low temperature
D
The electrophile involved in the reaction is ${NO}^{+}$

Solution

Nitrous acid is produce when sodium nitrate is reacted with acid. The nitrous acid can produce nitrosonium ion as electrophile. The tertiary amine given undergoes electrophilic substitution reaction with electrophile. The para substituted product is formed as major product.

${NaNO}_{2} + HX \to {HNO}_{2} + NaX$

$2 {HNO}_{2} \to {NO}^{+} + {NO}_{2}^{-} + H_{2} O$

$∴$ Statement $(2)$ is incorrect

Hence, the correct answer is option: 'B'.
