Question

What is the difference between non-polar covalent bonds and polar covalent bonds?

Question 6 options:

	Polar covalent bonds involve the sharing of one pair of electrons while non-polar covalent bonds involve the sharing of two or more pairs of electrons.
	Polar covalent bonds involve an equal sharing of electrons while non-polar covalent bonds involve an unequal sharing of electrons.
	Polar covalent bonds involve the gain and loss of an electron while non-polar covalent bonds involve a sharing of electrons.
	Polar covalent bonds involve an unequal sharing of protons while non-polar covalent bonds involve an equal sharing of protons.
	Polar covalent bonds involve an unequal sharing of electrons while non-polar covalent bonds involve an equal sharing of electrons.

Answer 1

both polar and non polar Covalent bond involves sharing of one pair of electron

Electrons are not transferred here since it is covalent bond. So there is no gain and loss of electrons as in ionic bond

In polar covalent bond these electrons are shared unequally in such a way that more electronegative element of bond is closer to shared electrons

Answer:

Polar covalent bonds involve an unequal sharing of electrons while non-polar covalent bonds involve an equal sharing of electrons.
