MCQ
Which of the following set contains species having same angle around the central atom?
- A$SF_4, CH_4 , NH_3$
- B$NF_3 , BCl_3 , NH_3$
- C$BF_3 ,NF_3 , AlCl_3$
- ✓$BF_3 , BCl_3 , BBr_3$
In all these molecules, central atom has $sp ^2$ hybridization so all have bond angle of $120^{\circ} C$
But due to presence of lone pair on $NF _3$ and $NH _3$ they shows lower angle.
