Question

Statement I F -atom has a less negative electron affinity than Cl-atom.
Statement II Additional electrons are repelled more effectively by 3p-electrons in Cl-atom than by 2p-electrons in F-atom.

• A. Statement I is true; Statement II is true; Statement II is the correct explanation of Statement I.
• B. Statement I is true; Statement II is true; Statement II is not the correct explanation of Statement I.
• C. Statement I is true; Statement II is false.
• D. Statement I is false; Statement II is true.

Answer 1

The correct option is C Statement I is true; Statement II is false.

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 3 p-electrons in Cl-atom.
