Given below are two statements: Statement I: The covalency of oxygen is generally two but it can exceed upto four. The oxidation state of oxygen in SO₂ is -2 and in OF₂ it is +2 . Statement II: The anomalous behaviour of oxygen when compared to the other elements of group 16 is due to its small size and high electronegativity. In the light of the above statements, choose the correct answer from the options given belo

Options

  1. ABoth Statement I and Statement II are true
  2. BBoth Statement I and Statement II are false
  3. CStatement I is true but Statement II is false
  4. DStatement I is false but Statement II is true

Correct answer

A. Both Statement I and Statement II are true

Step-by-step solution

Statement I: The electronic configuration of oxygen is 1s² 2s² 2p⁴ . Due to the absence of d-orbitals, its maximum covalency is limited to four (using one 2s and three 2p orbitals). Its covalency is generally two, but it can exceed two and go up to four in certain compounds. In SO₂ , oxygen is more electronegative than sulphur, so its oxidation state is -2 . In OF₂ , fluorine is more electronegative than oxygen, so the oxidation state of oxygen is +2 . Thus, Statement I is true. Statement II: Oxygen differs from th
