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.

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

Text Solution

Verified by Experts

The correct Answer is:
C
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.
