Question

Explain the hybridisation in SF₆ molecule.

Answer 1

1. In SF₆, the sulphur atom undergoes sp³d² hybridisation.
2. One 3s, three 3p, and two 3d orbitals of sulphur mix to form six sp³d² hybrid orbitals.
3. These six hybrid orbitals form six S-F bonds arranged octahedrally.
4. The molecule has an octahedral shape due to equal repulsion between bonding pairs.
5. This explains the high coordination number and symmetry in SF₆ molecule.
