In which of the following arrangements is the order not according to ...
As we move from left to right across a period, ionisation enthalpy increases with increasing atomic number. So, the order of increasing ionisation enthalpy should be B < c="" />< n="" />< />
But, N (1s2 2s2 2p3) has a stable half filled electron configuration. So, ionisation enthalpy of nitrogen is greater than oxygen. So, the correct order of increasing first ionisation enthalpy is B < c="" />< o="" />< />
Hence, the order indicated in the option (2) is correct.
