Wow many pairs of electrons are shared in the

following types of covalent bonds?

a. a single bond

b. a double bond

c. a triple bond

The Explanation is Given below.

Explanation:

Covalent bond:

Covalent bond is formed by mutual sharing of electrons. This mutual sharing of electrons occurs in such a way that each of the combining atom acquires the stable electronic configuration of the nearest noble gas.

a. A single bond:

A single bond is formed when each of the two combining atom share one electron each.

Example: Hydrogen bonding, H - H

b. A double bond:

A double bond is formed when atoms contribute two electrons each.

Example: Oxygen bonding, O=O

c. A triple bond:

A triple bond is formed on each item contributes three electrons each.

Example: Nitrogen bonding, N≡N
