Statement I : The first ionisation energy of Be is greater than that of B.
Statement II : 2p-orbital is lower in energy than 2s.

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 the reason is not the correct explanation of the assertion

C

If assertion is true but reason is false

D

If both assertion and reason are false.

Verified by Experts

The correct Answer is:

C

Be has fully `2s^(2)` orbital which gives a relatively more stable electronic configuration.
