Assertion (A) : The first IE of Be is greater than that of B
Reason (R ) : `2p` orbitals is lower in energy than `2s`

A

If both (A) and (R ) correct and (R ) is the correct explanation for (A)

B

If both (A) and (R ) correct and (R ) is the correct explanation for (A)

C

If (A) is correct but (R ) is incorrect

D

If (A) is incorrect but (R ) is correct

Text Solution

Verified by Experts

The correct Answer is:
C
Be has oionisation energy because Be (atomic number `4 = 1s^(2)2s^(2)` required higher energy to rfemove an electron from filled's orbital
