The molecule having smallest bond angle is

1.	The molecule having smallest bond angle is
Answer» `AsCl_(3)` `SbCl_(3)` `PCl_(3)` `NCl_(3)` SOLUTION :`SbCl_(3)` As we move down the group the size of atom increases and as size of central atom increases, lone pair-bond pair repulsion also increases. Thus bond angle decreases. Increasing order of ATOMIC radius : `N lt P lt As lt Sb ` Decreasing order of bond angle : `NCl_(3) GT PCl_(3) gt AsCl_(3) gt SbCl_(3)`
