Question

c) Give two examples to show anomalous behavior of oxygen. ​

Answer 1

(i) It forms only one oxoacid as compared to other halogens that form a number of oxoacids.

(ii) Ionization enthalpy, electronegativity, and electrode potential of fluorine are much higher than expected.

Answer 2

Explanation:

Reasons for the anomalous behavior of oxygen are given below.

1) Oxygen is small in size.

2) Oxygen has high electronegativity.

3) The valence shell of oxygen lacks vacant d orbitals.
