Assertion : All F-S-F angles in SF₄ are greater than $9 0^{\circ}$ but less than $18 0^{\circ}$ .

Reason : The lone pair-bond repulsion is weaker than bond pair-bond repulsion.

Options:

Answer:

Solution:

Assertion is correct due to trigonal bipyramidal electron geometry and see-saw molecular geometry. Reason is incorrect; LP-BP repulsion is stronger than BP-BP.
