Which of the following covalent halides undergoes hydrolysis such that the central atom accepts the — Periodic Table and Periodicity Chemistry Question

💡 Solution & Explanation

In $PCl_3$, Cl is more electronegative than P, so Cl takes $H^+$ (forming $HCl$) and P takes $OH^-$. In $NCl_3$, N takes $H^+$ due to steric/EN reasons, forming $NH_3$ and $HOCl$.
