Which statement explains why the solubility of carboxylic acid in water decreases when going down the homologous series?
The hydrocarbon part becomes larger and more significant
The formation of dimers between two carboxylic acid molecules
The boiling point of carboxylic acid increase
The hydrogen bonds increase the attractive forces between molecules
