What is a covalent bond?
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 a 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 a double covalent bond.
Example of Double covalent bond:
O2 , CO2 etc.
Triple covalent bond:
Sharing of three electron pairs results in the formation of a 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 a non-polar covalent bond.
For example HF, HCl, HBr, H2O etc.
Electronegativity difference and produce partial charges in polar molecules.
Examples of Polar Bond:
Watch Now : (Is HF Polar or Nonpolar) in Urdu /Hindi.
Watch Now: Is H2O Polar or Nonpolar in Urdu /Hindi.
Non-Polar Covalent bond
equal sharing of electrons results in the formation of a non-polar covalent bond.
For example H2, Cl2, F2, O2 etc.
Having no electronegativity difference and equal sharing/charge distribution in nonpolar molecules.
The characteristics of stable covalent compounds are largely determined by the nature of their covalent bonds. A covalent bond has several features and characteristics:
What a covalent bond is and what it does?
- formed by atoms sharing electrons
- Synthesized by the combination of two nonmetals or of a nonmetal and a metalloid
- Multiple covalent bonds between the same two atoms are possible.
- It takes a lot of effort to break the bond.

Frequently Asked Questions-FAQ
What is ionic and covalent bond?
In contrast to the covalent bond, which forms between two nonmetals, an ionic bond is established between a metal and a nonmetal.
How is a covalent bond formed?
When two atoms share electron pairs with one another, they form a covalent bond.
What elements form a covalent bond?
Typically, nonmetals form covalent bonds with one another. Two hydrogen atoms are singly linked to one oxygen atom in water (H2O) because each H and O atom shares a pair of electrons.
Is water a covalent bond?
In water (H2O), two hydrogen atoms are singly bonded to one oxygen atom; each H and O atom shares a pair of electrons to form a water molecule.
What are the 10 examples of covalent bonds?
Examples of covalent compounds are provided below.
- Hydrogen (H2) Hydrogen (H) is the simplest of all elements.
- Oxygen O2
- Ozone O3
- Nitrogen N2
- Water H2O
- phosphorus trichloride PCl3
- Carbon Dioxide CO2
- Methane CH4
- Ammonia NH3
- Carbon Monoxide CO
