Assertion: F atom has less electron afffinity than Cl atom.
Reason: Additional electrons are repelled more strongly by 3p electrons in Cl atom than by 2p electrons in F atom.

A

If both assertion and reason are true annd the reason is the correct explanation of assertion

B

If both assertion and reason are true but reason is not the correct explanation of assertion

C

If assertion is true but the reason is false

D

if assertion is false but the reason is true

Text Solution

Verified by Experts

The correct Answer is:
C
Due to small size of F atom added electron is replaced more strongly by 2p electrons than in case of Cl atom.
