The incorrect statement regarding the reaction given below is

Options

AThe product ‘ $B$ ’ formed in the above reaction is $p$ -nitroso compound at low temperature
B‘ $B$ ’ is $N$ -nitroso ammonium compound
CThe reaction occurs at low temperature
DThe electrophile involved in the reaction is ${NO}^{+}$

Correct answer

B. ‘ $B$ ’ is $N$ -nitroso ammonium compound

Step-by-step 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.

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

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

The incorrect statement regarding the reaction given below is

$∴$ Statement $\left(2\right)$ is incorrect
