Interpretation: The difference in the solubility of the given compounds in dilute sodium hydroxide is to be explained. Concept introduction: The solubility of the compounds depends upon the properties that are physical and chemical of the solvent and solute. The solubility of the compounds depends upon the given structural features below. 1. The compound with less number of carbon atoms is more soluble in water. 2. The compact or branched structures of the compound are more soluble in water than the linear structure of the compound. 3. The solubility increases with more hydrogen bonding group in the structure of the compound. 4. Ionic compound is more soluble in water than non-ionic compound.
