Detailed explanation-1: -A carbon atom is tetravalent, I.e. it can form four covalent bonds.
Detailed explanation-2: -The four covalent bonding positions of the carbon atom can give rise to a wide diversity of compounds with many functions, accounting for the importance of carbon in living things. Carbon contains four electrons in its outer shell. Therefore, it can form four covalent bonds with other atoms or molecules.
Detailed explanation-3: -There is no 4 bond formed between carbon because of the carbon electron orbitals. Since it has 4 valence electrons, it needs 4 more to electrons to fill its outer energy level.
Detailed explanation-4: -Carbon contains four electrons in its outer shell. Therefore, it can form four covalent bonds with other atoms or molecules.
Detailed explanation-5: -Thus the maximum number of covalent bonds is seven. Note: Due to the sharing of electrons, the covalent bond is the strongest bond.
