Current Question (ID: 8063)

Question:

$\text{In which of the following molecules are all the bonds not equal?}$

Options:

1. $\text{ClF}_3$ (Correct)
2. $\text{BF}_3$
3. $\text{AlF}_3$
4. $\text{NF}_3$

Solution:

$\text{HINT: Trigonal - bipyramidal geometry has unequal bond lengths.}$ $\text{Explanation:}$ $\text{1. Due to trigonal -bipyramidal geometry of ClF}_3 \text{ molecule}$ $(\text{sp}^3\text{d hybridisation}),\text{this molecule is T-shaped and due to the presence of both axial (longer bonds) and equatorial bonds (shorter bonds), bond lengths are unequal.}$ $\text{2. BF}_3 \text{ and AlF}_3 \text{ show trigonal planar structure due to sp}^2\text{-hybridisation.}$ $\text{3. NF}_3 \text{ shows pyramidal geometry due to sp}^3 \text{ hybridisation.}$
