Understanding Sulphur's Maximum Valency Explained

Learn why sulphur has a maximum valency by expanding its octet and using d orbitals for bonding.

0 views

Sulphur can have a maximum valency due to its ability to expand its octet. In addition to the s and p orbitals, sulphur can utilize empty d orbitals in its third energy level to form more than four covalent bonds. This allows it to achieve valencies greater than its usual 2 or 6, especially in compounds like sulphur hexafluoride (SF6).

FAQs & Answers

  1. What is the maximum valency of sulphur? Sulphur can exhibit a maximum valency of 6 by utilizing its d orbitals.
  2. How does sulphur expand its octet? Sulphur expands its octet by using its empty d orbitals to form additional covalent bonds.
  3. What compounds exhibit sulphur's maximum valency? Compounds like sulphur hexafluoride (SF6) demonstrate sulphur's capability to have a maximum valency.
  4. Why is the d orbital significant for sulphur? The d orbital allows sulphur to form more than four covalent bonds, which is crucial for its maximum valency.
