Explanation:
Detailed explanation-1: -Carbon has four valence electrons, so it can achieve a full outer energy level by forming four covalent bonds.
Detailed explanation-2: -To achieve stability, carbon must find four more electrons to fill its outer shell, giving a total of eight and satisfying the octet rule. Carbon atoms may thus form bonds to as many as four other atoms.
Detailed explanation-3: -For making four bonds, eight electrons would have to be squeezed in and such a system is highly unstable energetically. So, C-C quadruple bonds do not exist.
