$(CH_3)_2NH + NaNO_2 + HCl \rightarrow (CH_3)_2N-N=O + NaCl + H_2O$

Vedclass · Answer

(D) The reaction of secondary aliphatic amines with nitrous acid $(HNO_2)$ produces $N$-nitrosamines,which are yellow oily compounds. The reaction is: $(CH_3)_2NH + HNO_2 \rightarrow (CH_3)_2N-N=O + H_2O$. Option $D$ is incorrect because the reaction of dimethylamine with nitrous acid (generated from $NaNO_2 + HCl$) forms $N$-nitrosodimethylamine,not the structure implied by the notation in the option. Furthermore,the reaction shown in the option is chemically inaccurate regarding the products and stoichiometry for the given reactants.
