Which among the following molecules is (a) involved in sp³d hybridization, (b) has different bond lengths and (c) has lone pair of electrons on the central atom?

Hybridization and Bond Lengths in SF4 | JEE Main PYQ | Chemical Bonding

(A) XeF₄

(B) XeF₂

(D) SF₄

Correct Answer: SF₄

Explanation

In SF₄, sulfur undergoes sp³d hybridization with one lone pair, resulting in see-saw geometry.

Due to lone pair–bond pair repulsion, axial and equatorial S–F bonds have different bond lengths.

Hence SF₄ satisfies all the given conditions.
