Which of the following trihalide are hydrolysed by nucleophilic attack of water ?
(1) BF 3 (2) NF 3 (3) PCl 3 (4) AsCl 3
Text Solution
Verified by ExpertsThe correct answer is:
C
BF 3 is not hydrolysed due to p π – p π bonding bond strength of B – F bond increases. NF 3 is not hydrolysed because nitrogen do not have vacant d-orbitals. PCl 3 and AsCl 3 are easily hydrolysed because water molecules are able to coordinate with vacant d orbitals present in them.
