The hybridization state of the central atom in `HgCl_2` is

A

`sp`

B

`sp^2`

C

`sp^3`

D

`dsp^2`

Text Solution

Verified by Experts

The correct Answer is:
A
The ground-state electron configuration of `Hg` is `[Xe]4f^(14)5d^(10)6s^2`. Therefore, the `Hg` atom has two valence electrons (the `6s` electrons). Steric number of `Hg` is `2+0=2` which is confirmed by its Lewis structure
`Cl-Hg-Cl`
There are no lone pairs on the `Hg` atom. The molecule has linear geometry. We conclude that `Hg` is sphybridized because it has the geometry of the two sp hybrid orbitals.
