Solution
The correct option is A Ne > O > F > N
Second IE required to remove an e− for a 1+ cation in the gaseous state,
A+(g)⟶A2++e−
IE2 is affected by the size, effective nuclear charge and electronic configuration. So, on moving from N to Ne size of ion decreases, thereby increasing the IE.
⟶F+ is having less IE2 than O+ due to the interelectronics repulsion due to its' high electronegativity, it requires comparatively less energy to remove e− from its' outer shell.
