Covalent Bond :Definition and Examples – Digital Kemistry

What is a covalent bond?

Covalent bond formed by the mutual sharing of electrons between the atoms.

TYPES OF COVALENT BONDS

Covalent Bonds on the basis of electron pairs:

Single Covalent Bond

Double Covalent Bond

Triple Covalent Bond

Single covalent bond:

Sharing of one electron pair results in the formation of single covalent bond.

Identification & Representation:

Example of Single covalent bond:

H2 ,Cl2 ,F2 ,CH4 etc..

Double covalent bond:

Sharing of two electron pairs results in the formation of double covalent bond.

Example of Double covalent bond:

O2 ,CO2 etc.

Triple covalent bond:

Sharing of three electron pairs results in the formation of triple covalent bond.

Example of Triple covalent bond:

N2 ,C2H2 etc.

Types of Covalent Bonds on the basis of Electronegativity Difference:

Polar Covalent bond

Non-Polar Covalent bond

Polar Covalent bond

unequal sharing of electrons results in the formation of non-polar covalent bond.

For example HF , HCl , HBr, H2O etc.

Electronegativity difference

Produce partial charges

Examples of Polar Bond:

  1. HF Watch Now : (Is HF Polar or Nonpolar) in Urdu /Hindi.

2. H2O Watch Now : Is H2O Polar or Nonpolar in Urdu /Hindi.

Non-Polar Covalent bond

equal sharing of electrons results in the formation of non-polar covalent bond.

For example H2, Cl2 , F2 , O2 etc.

Having  no electronegativity difference

Equal  sharing / charge distribution
