Along the period `(rarr)` atomic`//`ionic radii and metallic character decreases while `IE`, `EN` , non-metallic character and oxidising power increases. Down the group `(darr)`, atomic`//`ionic radii, metallic character and reducing character increase while `IE` and `EN` decrease. However, `Delta_(eg)H^(ɵ)` becomes less negative down a group but more negative along a period.
Correct order of `IE_(2)` of the following is

Options

A. `F gt O gt N gt C`
B. `O gt N gt F gt C`
C. `O gt F gt N gt C`
D. `C gt N gt O gt F`.

Answer

C
