Benzylamine () possesses an aromatic ring, yet responds dramatically differently to nitrous acid comAmines Chemistry Question

Question

Benzylamine ($C_6H_5CH_2NH_2$) possesses an aromatic ring, yet responds dramatically differently to nitrous acid compared to aniline. When treated thoroughly with $HNO_2$ between $0-5^\circ C$, what is the exact identity of the overwhelmingly dominant final organic product?

Answer: B

💡 Solution & Explanation

Benzylamine is physically an aliphatic amine because the nitrogen relies strictly on an $sp^3$ hybridized carbon, completely lacking resonance stabilization with the ring. Thus, the initially generated diazonium salt is violently unstable (just like standard primary aliphatics), rapidly releasing $N_2$ and capturing water to forcefully yield strictly benzyl alcohol.
