Answer to Question #99476 in General Chemistry for Brittany Wallace

Question

1. What is the hybridization of the central atom in SF4?
What are the approximate bond angles in this substance?

2. What is the hybridization of the central atom in BrF5?
What are the approximate bond angles in this substance?

Answer 1

1. SF4

Hybridization of the central atom (S) is sp3d

Bond angles are:

Electron pair on the central atoms pushes the bonds S-F, what leads to the change in bond angles.

2.BrF5

Hybridization sp3d2

Bond angles:

The bond angle (84.8⁰ ) differs from ideal angle of 90⁰ because of electron pair repulsion.
