What are Intermolecular forces ?

Explanation:

An intermolecular force is the force that mediates interaction between molecules, including the electromagnetic forces of attraction or repulsion

The forces of attraction between atoms, molecules, and ions when they are placed close to each other is called Intermolecular force.

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.
