Which one of the following is an incorrect statement?

A

The ionization potential of nitrogen is greater than that of oxygen

B

The electron affinity of fluorine is greater than that of chlorine.

C

The ionization potential of beyllium is greater than that of boron.

D

The electronegativity of fluorine is greater than that of chlorine.

Text Solution

Verified by Experts

The correct Answer is:
B
On account of quite small size of `F` (relative to that of `C1`), the incoming electron experiences quite large `e^(-)-e^(-)` repulsion and hence, the electron gain enthalpy of `F` is less negative than that of `C1: C1 (-349 kJ mol^(-1))gt F (-333)`.
