d. CH2F2
e. H2O

Expert Answer

Step 1

In the formation of the chemical bond with the same or different elements, all elements tend to complete their octet configuration. It is known as Octet rule. The octet configuration (means 8 electrons in the valence shell of the bonded atom) can be achieved by either sharing of electrons to form a covalent bond or by the complete transfer of electrons that leads to the formation of an ionic bond.

Step 2

The chemical bond that is formed between two elements with large difference of electronegativity is said to be a polar bond. In a polar bond, the more electronegative element gets the partial negative charge and less electronegative element gets the partial position charge.

Step 3

The non-polar bond is formed between elements with same electronegat...
