Question

The correct order of electron affinity (considering only magnitude) of B, C, N, O is:

• A. $O>C>N>B$
• B. $B>N>C>O$
• C. $O>C>B>N$
• D. $O>B>C>N$

Answer 1

The correct option is A $O>C>N>B$

$Ea=B<N<C<O$

$Ea$ increases in period from left to right expect partially filled configuration which requires less affinity towards electron$.$
