Which of the following order is correct ...

Which of the following order is correct for the first ionozation potential of `B, C`, and `N`?

A

`B gt C gt N`

B

`N gt C gt B`

C

`N gt C lt B`

D

`N lt C lt B`

Text Solution

Verified by Experts

The correct Answer is:
B
These elements belong to the `2nd` period, and across the period, the inoization enthalpy (in general) increases on account of increase of effective nuclear charge:
`N(1402 kJ mol^(-1)) gt C (1086) gt B (801)`
