Question

Give the following for SO2 and BrF5:

(a) Number of domains on central atom (b) Domain geometry (c) Molecular geometry (d) Hybridization of central atom

Answer 1

The given molecules are SO2 and BrF5.

Step-by-step explanation:

Consider the molecule SO2:

The central atom is S.

The number of domains on S in this molecule is three.

Domain geometry is trigonal planar.

But there is a lone pair on the central atom.

So, according to VSEPR theory,

the molecular geometry becomes bent or V-shape.

Hybridization on the central atom is

`sp^(2)`.

Consider the molecule BrF5:

The central atom is Br.

The number of domains on the central atom is six.

Domain geometry is octahedral.

But the central atom has a lone pair of electrons.

So, the molecular geometry becomes square pyramidal.

The hybridization of the central atom is
`sp^(3) d^(2)`.

The shapes of SO2 and BrF5 are shown below:
