Assertion: The first ionization energy of Be is greater than that of B.
Reason: 2p-orbital is lower in energy than 2s-orbital.

A

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

B

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

C

If assertion is true but reason is false.

D

If the assertion and reason both are false.

Text Solution

Verified by Experts

The correct Answer is:
C
Assertion is true but reason is false. Be has fully filled `2s^(2-)` orbital which gives a relatively more stable electronic configuration.
