For the second period elements the correct increasing order of first ionisation enthalpy is:

ALi < B < Be < C < N < O < F < Ne
BLi< Be < B < C < O < N < F < Ne
CLi < Be < B < C < N < O < F < Ne
DLi < B < Be < C < O < N < F < Ne
Correct Answer

Solution


′Be′ and ′N′ comparatively more stable valence subshell than 'B' and 'O'.

Hence, the correct order of first ionisation enthalpy is:

$$Li
