HELP!! Which of the following statements best explains why oil does not dissolve in water?
A.
Polar water molecules attract each other more strongly than they attract nonpolar oil molecules.
B.
Polar water molecules attract each other less strongly than they attract nonpolar oil molecules.
C.
Water molecules and oil molecules are both polar and attract each other equally well.
D.
Water molecules and oil molecules are both nonpolar and attract each other equally well.

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.
