प्रश्न
Why are alkyl halides insoluble in water?
उत्तर
Alkyl halides are very slightly soluble in water. This is because the interaction of haloalkane and water molecules is not as strong as the interaction among water molecules. When alkyl halides dissolve in water, the energy released is not sufficient to overcome the attractions between the alkyl halides molecules and to break the hydrogen bonds between water molecules. Thus, alkyl halides are insoluble in water.
