Question

Name the dominant intermolecular force for the following pure substance molecule (reacts only with other identical molecules) and whether generally soluble in water or gasoline.

answer choices:

Dipole-Dipole, Soluble in gasoline

London Forces, Soluble in gasoline

Hydrogen Bond,   Soluble in gasoline

Ionic,   Soluble in gasoline

Hydrogen Bond,   Soluble in water

Ionic,   Soluble in water

London Forces, Soluble in water

Dipole-Dipole, Soluble in water

Dipole-Dipole, Soluble in gasoline

London Forces, Soluble in gasoline

Hydrogen Bond,   Soluble in gasoline

Ionic,   Soluble in gasoline

Hydrogen Bond,   Soluble in water

Ionic,   Soluble in water

London Forces, Soluble in water

Dipole-Dipole, Soluble in water

Explanation / Answer

For benzoic acid, due to the presence of OH group, it can form hydrogen bonds and become soluble in water. The compound should be able to form hydrogen bonds to make it soluble in water.

It is also soluble in gasoline, as it can have london forces of interaction. Due to the presence of polar and non-polar groups available in benzoic acid, it can have temporary dipoles which leads to London forces between the molecules. Thus property makes it soluble in gasoline.
