`SF_(2),SF_(4)` and `SF_(6)` have the hybridisation at sulphur atom respectively as .

Options

A. `sp^(2), sp^(3), sp^(3), d^(2)`
B. `sp^(3), sp^(3), sp^(3) d^(2)`
C. `sp^(3), sp^(3), d, sp^(3) d^(2)`
D. `sp^(3), spd^(2), d^(2) sp^(3)`

Answer

C

Explanation

No. of hybrid orbitals formed `(X) = (1)/(2)` [Valence electrons of central atom (VE) + No. of monovalent atoms/groups (MA) -Charge on polyatomic cation
(c) + Charge on polyatomic anion (a)
For `SF_(2) , X= (1)/(2) (6 + 2 - 0 ) = 4 ` ,
Hybridisation = =`sp^(3)`
For `SF_(2) , X = (1)/(2) (6 + 4 - 0 ) = 5 `
Hybridisation = ` sp^(3) d `
For ` SF_(6), X = (1)/(2) (6 + 6 - 0 ) = 6 `
Hybridisation = ` sp^(3) d^(2)`
