Question

Mention the state of hybridization of central atom? 1.SF6

Answer 1

`d^2 sp^3`

Explanation:

Hybridization state increases as steric number (number of bonds+ number of lone pairs) increases. Hybridization increases as follows:

SN=1 or 2, hybridization= `sp`
SN=3, hybridization= `sp^2`
SN=4, hybridization= `sp^3`
SN=5, hybridization= `dsp^3`
SN=6, hybridization= `d^2 sp^3`

Since the S atom in `SF_6` is bonded to six atoms and has zero lone pairs, its steric number is 6, and its hybridization is `d^2 sp^3`
