Assertion: `F` atom has a less negative electron affinity than `CI` atom.
Reason: Additional electrons are repelled more effectival by `3p` electrons in `CI` atom than by `2p` electrons in `F` atom.

Options

A. Statement 1 is true, statement 2 is true, statement 2 si a correct explanation for statement 5
B. Statement 1 is true, statement 2 is true, statement 2 is not a correct explanation for statement 5
C. Statement 1 is true, statement 2 is false
D. Statement 1 is false, statement 2 is true

Answer

C

Explanation

F has slightly less electron affinity than chlorine because F has very small atomic size (only two shells). Hence results in less evolution of energy in the formation of `F^(-)` ion. Statement 1 correct but statement 2 incorrect.
