Detailed explanation-1: -A carbon atom is tetravalent, I.e. it can form four covalent bonds.
Detailed explanation-2: -A carbon atom can bond with four other atoms and is like the four-hole wheel, while an oxygen atom, which can bond only to two, is like the two-hole wheel. Carbon’s ability to form bonds with four other atoms goes back to its number and configuration of electrons.
Detailed explanation-3: -Carbon contains four electrons in its outer shell. Therefore, it can form four covalent bonds with other atoms or molecules.
Detailed explanation-4: -What is the maximum number of double bonds that a carbon atom (C) can form? Explanation: Each carbon atom has 4 valence electrons that it can share with other atoms. Since each double bond corresponds to a pair of electrons, the carbon atom can form only 2 double bonds.
