Question

carbon cannot from ionic bond give reasons ????

Answer 1

carbon has valency 4 to attend noble gas configuration it need to gain or lose 4 electrons so that it would form ionic compound

1.if it gain 4 electrons it would be difficult for nucleus to hold 6 protons on to 10 electrons.

2.if it lose 4 electrons it would require lot of energy tolose 4 electrons from nucleus holding 6 protons on to just 2 electrons.

Thus carbon doesnt form ionic compounds.

Answer 2

because carbon is too small and didn't have much energy. carbon can't gain 4 electrons and cannot release 4 electrons becoz gaining and releasing of electrons need too much energy which carbon didn't have.
