Question

Explain anomolous behavior of oxygen

Answer 1

Answer:

Oxygen forms strong hydrogen bonding in H2O which is not found in H2S. Also, the maximum covalency of oxygen is four, whereas in a case of other elements of the group, the valence shells can be expanded and covalency exceeds four.

Reasons for the anomalous behaviour of oxygen are:

• Small size and high electronegativity

• Absence of d-orbitals
