The molecule having the smallest bond angle is-

A

`AlCl_(3)`

B

`SbCl_(3)`

C

`PC l_(3)`

D

`NC l_(3)`

Text Solution

Verified by Experts

The correct Answer is:
B
Bond angle of a molecule increases with the increases in electronegativity or with decrase in size of the central atom. Hence, the correct order of bond angle is: `SbCl_(3) lt AsCl_(3) lt PC l_(3) lt NC l_(3)`.
