In${\mathrm{SF}}_4,\mathrm{S}$  atom has  ${\mathrm{dsp}}^{\text{x}}$ hybridization. What is the value of x?

Valence shell of electrons of 'S' = 6(3s²3p⁴)

Number of bond pairs (BP) =4

Number of lone pairs(LP)=$\frac{1}{2}(6-4)$ =1

Hybridization of 'S' in sp³d (4 B.P +1 L.P)

Total pairs =5

So, the value of x =3 sp^xd
