Apolar molecule contains?

a. ions.

b. a region of positive charge and region of negative charge.

c. only london forces.

d. no bonds.

A polar molecule contains a region of positive charge and a region of negative charge.

b. a region of positive charge and region of negative charge.

Explanation:

In polar molecules, the distribution of electrons among the covalently bonded atom is not even. Also, polarity is the difference in the electrical poles of a molecule. Hence, polar molecules consist of polar bonds.

In polar bonds, the electro negative difference between two atoms is mainly between 0.5 and 2.0. One of the famous examples of polar is water.

Examples of polar molecules are:

it is the most commonly accepted one

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
