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
Answer (as printed): D
Explanation
Among given compounds $\mathrm{NF_3}$ is not hydrolyse easily because, the more electro negative F atom strongly attracts the electrons present in N atom and they are no longer available to get hydrolysed.$\mathrm{BiCl_3}$ is not readily hydrolysed by water to give $\mathrm{BiOCl}$.
But BiOCl redissolve in conc. HCl to produce $\mathrm{BiCl_3}$ after evaporation. It has quasi molecular structure.$\mathrm{PCl_3}$ is easily hydrolysed by water.
