Question

If carbon have valency 4 so why 6 electrons are there. Why 8 electrons are not. Because 1 bond 2 electrons. So 8 electrons are needed.???

Answer 1

Answer:

To satisfy the Octet Rule, Carbon needs 4 more valence electrons. Since each Oxygen atom has 3 lone pairs of electrons, they can each share 1 pair of electrons with Carbon; as a result, filling Carbon's outer valence shell (Satisfying the Octet Rule).
