SF4 molecule exhibits sp3d hybridization with four bonding pairs and one lone pair, resulting in an asymmetrical geometry.

1. It has a see-saw geometry.
2. The net dipole moment is not zero.
3. Both the see-saw geometry and nonzero dipole moment are correct.
4. Neither of the statements is correct.

Correct answer: Both the see-saw geometry and nonzero dipole moment are correct.

Solution

SF4 has sp3d hybridization with a see-saw shape due to 4 bond pairs and 1 lone pair. The lone pair causes asymmetry, resulting in a net dipole moment (μ ≠ 0). Thus, both (a) and (b) are correct.
