Question

The electron affinities of N , O , S and Cl are (A) O ≈ Cl < N ≈ S (B) O < S < Cl < N (C) N < O < S < Cl (D) O < N < Cl < S

Chlorine being the group 17 element has maximum affinity. ' N ' has zero electron affinity because extra stability is associated with exactly half - filled orbitals. Sulphur has more electron affinity than ' O ' because the effect of small size of O atom is more than by the repulsion of electron already present in 2 p orbitals of O atom.

Q. The electron affinities of $N, O, S$ and $Cl$ are

$O \approx Cl < N \approx S$

$O < S < Cl < N$

$N < O < S < Cl$

$O < N < Cl < S$

Q. The electron affinities of N,O,S and Cl are

O≈Cl<N≈S

O<S<Cl<N

N<O<S<Cl

O<N<Cl<S

Q. The electron affinities of $N, O, S$ and $Cl$ are

$O \approx Cl < N \approx S$

$O < S < Cl < N$

$N < O < S < Cl$

$O < N < Cl < S$
