MCQ
The molecule having smallest bond angle is :
- A$NCl_3$
- B$AsCl_3$
- ✓$SbCl_3$
- D$PCl_3$
✓
Answer
Correct option: C.
$SbCl_3$
c
All the members form volatile halides of the type $A X_{3} .$ All halides are pyramidal in shape. The bond angle decreases on moving down the group due to decrease in bond pair-bond pair repulsion.
