Question

What are the polar and nonpolar covalent compounds?

Answer 1

Hint: In this we have to differentiate between polar and nonpolar covalent compounds through their definition, charge, melting/ boiling points and examples etc. Now you can easily answer the statement.
Complete step by step answer:
First of all let’s discuss what are covalent compounds. Covalent compounds are those compounds which are formed by the sharing of the electrons.
Now We will differentiate between the two i.e. the polar and nonpolar covalent compounds in the tabular form because it's an easy way to understand them and learn them.
Their difference is as below;

Sr No.	Property	Polar covalent compound	Non-polar covalent compound.
1.	Definition	They are those compounds which are formed between those substances which have different electronegativities.	They are those compounds which are formed between those substances which have the same electronegativities.
2.	Melting /boiling points.	They have high melting and boiling points.	They have low melting and boiling points.
3.	Charge	They consist of the charges i.e. negative and positive charges around the poles.	They do not carry any charge.
4.	Dipole moment	It shows dipole moment due to its polarity(i.e. positive-negative charges)	They have zero dipole moment.
5.	Bonding	Hydrogen bonding is present in these compounds.	It involves the Vander Waals forces.
6.	Examples	HCl, $N{{H}_{3}}$ etc.	${{N}_{2}}$, $CC{{l}_{4}}$ etc.

So, it’s easy to distinguish between the polar and nonpolar covalent compounds in the tabular form rather than in the paragraph form.

Note: Don’t get confused in the covalent and ionic compounds. Covalent compounds are those compounds which are formed by sharing of their electrons. Whereas on the other hand, ionic compounds are those compounds which are formed by the loss and gain of electrons.
