Question

Why graphite doesn't share its all four electrons? Explain why?

Answer 1

When a single bond is formed between carbon atoms , energy is released . Changing the molecule's electron arrangement to make a double bond releases more energy , but not as much as when the first bond was made . Making triple bond again releases energy , but again to lesser degree . However when the fourth bond is formed the electrons get overcrowded . Hence a quadrupled bond will essentially impossible . That's why graphite doesn't share it's all four electrons .

Hope it helps
