Assertion: `F` atom has less negative electron gain enthaply than `Cl` atom.
Reason: Additional electrons are repelled more effectively by 3 p-electrons in `Cl` than by `2` p-electrons in `F` atom.

Options

A. Both Statement I and Statement II are correct, Statement II is the correct explanation of Statement I
B. Both Statement I and Statement II are correct, Statement II is not the correct explanation of Statement I
C. Statement I is correct, Statement II is the incorrect
D. Statement I is incorrect, Statement II is the correct

Answer

C

Explanation

Statement I is true, Statement II is false.
F atom has slightly lower affinity for the electron than chlorine. It is due to the reason that additional electrons are repelled more effectively by 2p-electrons in F than by 3p-electrons in Cl-atom.
