Select the correct statement(s) about the sulphur dioxide molecule.

  1. AIt is bent with S in hybridisation
  2. BThe two S-O bonds are of equal length because of resonance
  3. CThe sulphur atom carries one lone pair of electrons
  4. DThe molecule is non-polar

Answer: A, B, C

has two bonding regions and one lone pair on S (three electron domains, ), giving a bent shape; the two canonical forms make the two S-O bonds equal. A bent molecule with polar bonds has a net dipole moment, so D is false.
