Likely bond angles of SF(4) molecule are...

Likely bond angles of `SF_(4)` molecule are :

A

`89^@, 117^@`

B

`120^@, 180^@`

C

`45^@, 118^@`

D

`117^@, 92^@`

Text Solution

Verified by Experts

The correct Answer is:
A
Sulphur in `SF_4` molecule undergoes `sp^3d` hybridization with one lone pair of electrons. Its geometry should be trigonal bipyramidal but due to one location is occupied by the lone pair so its actual geometry is irregular tetrahedral. Trigonal bipyramidal structure has the angles of 120° and 90° so `SF_4` will have angles lower than those. So possible answer is 89° and 117°.
