Question

Why change in ionisation enthalpy 1 more than ionisation enthalpy 2 mk?

Answer 1

Answer:

The second ionisation enthalpy of carbon is less than that of boron because after losing one electron the boron atom changes into B+ which has stable electronic configuration. As a result more energy is required to remove an electron from B+ than from C+.

Answer 2
