Question

Which is not the correct order for the stated property?

easy

Solution

Correct option is

F > O > N, first ionisation enthalpy

On moving along a period, ionisation enthalpy increases. Thus, the order of ionisation enthalpy should be as follows:

F > O > N

But N has half-filled configuration, therefore it is more stable than O and has higher ionisation enthalpy.
