Question

The correct order of ionisation energy of C, N, O, F is (A) C < N < O < F (B) C < O < N < F (C) C > O < N < F (D) F < N < C < O

Tardigrade Admin · Accepted Answer

Ionisation energy generally increases from left to right in a period but ionisation energy of nitrogen is greater than oxygen due to stable p3 configuration. Hence, the order is as C< O< N< F

Q. The correct order of ionisation energy of $C, N, O, F$ is

$C < N < O < F$

$C < O < N < F$

$C > O < N < F$

$F < N < C < O$

Ionisation energy generally increases from left to right in a period but ionisation energy of nitrogen is greater than oxygen due to stable $p^{3}$ configuration. Hence, the order is as

$C < O < N < F$
