To synthesize phenol from aniline, the amine must first be diazotized. What are the correct reagents — Alcohols Phenols and Ethers Chemistry Question

💡 Solution & Explanation

Diazotization of primary aromatic amines utilizes nitrous acid (generated from $NaNO_2$ and $HCl$). Because the resulting diazonium salt is highly unstable, the reaction must be performed strictly in an ice bath between $273\text{ K}$ and $278\text{ K}$ ($0-5^\circ\text{C}$).
