Normally carbon forms how many and what type of bonds?

Carbon generally forms four covalent chemical bonds.

Explanation:

Carbon is a chemical element that belongs to group 14 of the periodic table and has atomic number 6. It is a member of the p-block and is nonmetallic in nature.

The ground-state electronic configuration of carbon atom is 1s²2s²2p². Thus, it has 4 valence electrons and is said to be tetravalent.

Therefore, carbon generally forms four covalent chemical bonds.
