The order of first ionisation potential is C > Be > B. The reason is carbon is having more effective nuclear charge which attracts the outermost electron towards the nucleus more and need more energy
SHIVAANSHSINGH:
hope u understand
but s shell is nearer to nucleus due to which it will hold the electron more strongly as compared to p shell electron..... that is a fact as well
Sorry I didn't give right answer.next time I will think first then answer
reason is still not clear to me......... can someone please give me proper reason?
there are many factors affecting ionisation potential
so according to all u can't understand
the data are used to compare
ok .........
On moving left to right effective nuclear charge increases and carbon is in 14 group .size is small and more energy is needed to remove electron so it has more ionisation enthalpy.
Be although comes before boron but in beryillium electron have to be removed from s orbital and in boron electron removed from p orbital. So be has more I. E

Be>B>C is correct order
can u please explain the reason?
It will be like C>Be>B because on moving across period I. E increase and B has more I.E due to electron in s orbital
