Question

The maximum covalency of sulphur is ______.

Options

• 2

• 4

• 6

• 8

Answer 1

The maximum covalency of sulphur is 6.

Explanation:

Sulphur can expand its octet using vacant d-orbitals to form up to 6 bonds, as seen in compounds like SF₆. Although sulphur’s ground state allows 2 bonds, excitation promotes electrons to d-orbitals, enabling six bonds.
