| Assertion: F atom has less negative electron gain enthalpy than Cl atom. |
| Reason: Additional electrons are repelled more effectively by 3p electrons in Cl atom than by 2p electrons in F atom. |
A) If both assertion and reason are correct and reason is correct explanation for assertion.
B) If both assertion and reason are correct but reason is not correct explanation for assertion.
C) If assertion is correct but reason is incorrect.
D) If assertion is wrong, but reason is correct.
Correct Answer: C
Solution :
Correct reason. Due to very small size and high electron density, it is very difficult for the F atom to accept an extra electron from outside.
