Which of the following order of ionisation energy is correct?

A

`Be gt B gt C gt N gtO`

B

`B gt Be gt C gt O gtN`

C

`B lt Be lt C lt N lt O`

D

`B lt Be lt N lt C lt O`

Text Solution

Verified by Experts

The correct Answer is:
B
Ionisation energy increases across the period but due to stable half filled configuration of VA group, its I.E. is more than VI-A group.
