Polar covalent bond is a type of chemical bond where a pair of electrons is unequally shared between two atoms.

Non covalent bond on the other side is a type of chemical bonding where two atoms share a pair of electrons with each other.

Polar covalent bond are characterized by having an unequal distribution of electrons of two elements.

They also retain a positive and negative pole, which allows then to have some electronegativity.

On the other have non- covalent bonds are described as having electrons that are similar or nearly equal in terms of number of electrons, this characteristics makes them have none or less electronegativity.

Polar covalent bonds have a defined axis or axes, While non - polar covalent bonds lack the charge.

Polar covalent bonds have a charge ( having both positive and negative) poles, While non polar covalent bonds lack the charge.

Hello Dear.

Here is the answer---


Polar Covalent Bonds are those bonds in which the Electronegativity difference between the Combining atoms is large, thus the Shared Pair of the electrons are towards the atom having the higher electronegativity.

Examples 
⇒ Hydrogen Chloride (HCl), Water(H₂O), Ammonia(NH₃) etc.


Non Polar Covalent Bonds are those bonds in which the Electronegativity difference between the combining atoms is Zero or negligible, thus Shared Pairs of the electrons are equally distant from both the atoms.

 Examples Benzene(C
₆H₆,) Carbon Tetra chloride (CCl₄), Methane(CH₄), etc.


Properties of the Polar Covalent Bonds are →

1) Polar Covalent bonds Ionizes in the water.

2) Electrons are not at a equal Distance between the combining atoms. Electrons are raised towards the atom having the high electronegativity.

2) Aqueous Solutions of the Polar Covalent Compounds acts as the Electrolytes. They Conducts the electricity when water is added to it.

Properties of Non Polar Covalent Bond are →

1) Electrons in the Non-Polar Covalent Compounds are at a Equal Distance from the Combining atoms due to the negligible electronegativity difference.

2) They do not Ionizes in water.


Hope it helps.
