Will is learning about a new kind of plastic used to make models. He learns that infrared light is absorbed by the plastic, X-ray light is transmitted through the plastic, and visible light is reflected off the plastic. Will wonders if the plastic will melt if he shines the lights on it. Can light cause the plastic to melt? Why or why not? Does it matter what type of light he shines on the plastic?

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.
