Explain the solubility of haloalkanes in water and organic solvents.

(N/A) Solubility of haloalkanes in water: Haloalkanes are very slightly soluble in water (almost insoluble).
To dissolve haloalkanes in water,energy $(x)$ is required to overcome the dipole-dipole attractions between haloalkane molecules and the hydrogen bonds between water molecules.
When haloalkanes dissolve,new attractions are formed between haloalkane and water molecules,releasing solvation energy $(y)$.
This new attraction $(y)$ is not as strong as the original hydrogen bonds $(x)$ in water.
Therefore,the solubility of haloalkanes in water is very low.
Since the solvation energy $(y) < $ hydrogen bond energy $(x)$,haloalkanes remain almost insoluble and form a separate layer.
Solubility of haloalkanes in organic solvents: Haloalkanes tend to be soluble in organic solvents.
This is because the strength of the intermolecular attraction forces formed between polar haloalkane molecules and organic solvent molecules is comparable to the attraction forces between the haloalkane molecules themselves and between the solvent molecules themselves.
