Under review — part of this question (a structure or an option) is not clear in the source scan. 4AB is checking it against the original book; the answer shown may change.
Among the compounds A-D, those which hydrolyse easily are
(a)$\mathrm{NCl_3}$
(b)$\mathrm{NF_3}$
(c)$\mathrm{BiCl_3}$
(d)$\mathrm{PCl}_{3}$
Answer
Under review — not yet confirmed.
Answer: D
Answer: NCl₃, BiCl₃ and PCl₃.
Explanation
Answer: NCl₃, BiCl₃ and PCl₃ — NCl₃ → NH₃ + HOCl; BiCl₃ → BiOCl + 2HCl; PCl₃ → H₃PO₃ + 3HCl. NF₃ is kinetically inert to water: the N–F bonds are strong and N has no vacant orbitals.
