(a)
Interpretation:
The solubility of given substance in water and benzene is to be predicted.
Concept introduction:
The term soluble is used for a pair of substances that forms a homogenous mixture. The term insoluble is used for a pair that does not mix with each other. The solubility of a substance in a solvent depends on the “like dissolve like” principle. Polar-polar substance will mix in each other and non-polar and non-polar substance will mix each other.
