Question

Which of the following represent(s) the correct order of electron affinities ?
  1. F > Cl > Br > I
  2. N < C < O < F
  3. C < N < Cl < F
  4. C < Si > P > N

A
F > Cl > Br > I
B
N < C < O < F
C
C < N < Cl < F
D
C < Si > P > N
Solution
Verified by Toppr

Generally the electron affinity values of 3rd period elements are higher than the elements of 2nd period of the same group because of less inter-electronic repulsions. Atomic size, nuclear charge and electrons configurations also affect the electron affinity.
