Alkyl halides though polar, are immiscible with water, why ?

Explanation

Alkyl halides are polar molecules and therefore their. molecnles are held together by dipole-dipole forces. On the other hand the molecnles of `H_2O` are held together by hydrogen bonds. When alkyl halides are added to water, the new force of attraction between water and alkyl halides molecules are weaker than the force of attraction already existing between alkyl halide-alkyl halide molecules and water-water molecules. Hence alkyl halide are immiscible in water.
