Question

Discuss polar and non-polar covalent bonds with suitable examples.

Answer 1

Nonpolar covalent bonds are a type of bond that occurs when two atoms share a pair of electrons with each other. These shared electrons glue two or more atoms together to form a molecule. Like children who share toys, atoms involved in a nonpolar covalent bond equally share electrons. An example of a nonpolar covalent bond is the bond between two hydrogen atoms because they equally share the electrons. Another example of a nonpolar covalent bond is the bond between two chlorine atoms because they also equally share the electrons. Nonpolar covalent bonds are very strong bonds requiring a large amount of energy to break the bond.

Nonpolar covalent bonds are extremely important in biology. They form the oxygen we breathe and help make up our living cells. One kind of nonpolar covalent bond that is very important in biology is called a peptide bond. A peptide bond joins together chains of amino acids, which are involved in the construction of our DNA. Amino acids are comprised of several atoms like carbon, oxygen, nitrogen and hydrogen.
