Why carbon easily forms many bonds?

a) it can share six electrons in metallic bonds

b) it can share electrons in ionic bonds

c) it can share four electrons in hydrogen bonds

c) it can share four electrons in covalent bonds

The Correct Answer: C)

Because ...

Each carbon is identical, they all have four valence electrons, so they can easily bond with other carbon atoms to form long chains or rings. In fact, a carbon atom can bond with another carbon atom two or three times to make double and triple covalent bonds between two carbon atoms.
