Chemistry Question on Chemical bonding and molecular structure
In the structure of SF4, the lone pair of electrons on S is in.
A
Equatorial position and there are two lone pair – bond pair repulsions at 90º
B
Equatorial position and there are three lone pair – bond pair repulsions at 90º
C
Axial position and there are three lone pair – bond pair repulsion at 90º
D
Axial position and there are two lone pair – bond pair repulsion at 90º
Answer
Equatorial position and there are two lone pair – bond pair repulsions at 90º
Explanation
Solution
The correct answer is (A) : Equatorial position and there are two lone pair – bond pair repulsions at 90º
SF4 → sp3d hybridisation.
Fig.
The lone pair of electrons on S is in equatorial position and there are two lone pair-bond pair repulsions at 90°.
