In which of the following molecules are all the bonds not equal?
- $\mathrm{NF}_3$
- $\mathrm{ClF}_3$
- BF3
- $\mathrm{AlF}_{3}$
Solution
$\mathrm{BF}_3$ and $\mathrm{AlF}_3$ show a trigonal symmetric structure because of $s p^2$ hybridisation.
$\mathrm{NF}_3$ shows pyramidal geometry because of $s p^3$ hybridisation.
