Question

In which of the following molecules d-orbitals are used in hybridisation & also in ∏−∏− bonding ?

Answer 1

Answer:

S atom in SF

4

is bonded to four Fluorine atoms and has one lone pair (S has 6 valence electrons; four of them went in bonding with four Fluorine atoms while the other two remained as a lone pair on S atom). All of them are in hybridized orbitals. There are five such orbitals. So the hybridization is sp

3

d. The d−orbital involved in hybridization of SF

4

is d

z

2

. Always d

z

2

takes part in sp

3

d hybridisation.
