Which of the following statements is correct?

Options

A. The magnitude of the second electron affinity of sulphur is greater than that of oxygen
B. The magnitude of the second electron affinity of sulphur is less than of oxygen
C. The first electron affinities of bromine and iodine are approximately the same
D. The first electron affinity of fluorine is greater than that of chlorine

Answer

B

Explanation

`O^(-) overset(e^(-) )(to) O^(-2)` EGE = + ve , `S^(-) overset(e^(-) )(to) S^(-2)` EGE = +ve
EGE is positive when an electron is added to anion (as repulsion between negative charges) and EGE is more (+ve) in case of `O^(-)` because of it small size , so charge density increases & hence more repulsion.
