The ease of hydrolysis of trichlorides of group - 15 elements decrease in the order

A

`NCl_(3) gt PCl_(3) gt AsCl_(3) gt SbCl_(3) gt BiCl_3`

B

`PCl_(3) gt NCl_(3) gt AsCl_(3) gt SbCl_(3) gt BiCl_3`

C

`AsCl_(3) gt NH_3 gt PCl_(3) gt SbCl_3 gt BiCl_3`

D

`SbCl_(3) gt BiCl_3 gt PCl_3 gt NCl_(3) gt AsCl_3`

Text Solution

Verified by Experts

The ease of Hydrolysis of halides depends up on
i) Polarity of E -X bond
ii) availability d - orbitals either on E (or) X
Down the group metalic nature of central atom decreases and degree of Hydrolysis decreases:
`NCl_(3) gt PCl_(3)gt ASCl_(3)gt SbCl_3 gt BiCl_3`
