Why alkyl halides though polar are immiscible with water?
Advertisements
उत्तर
Alkyl halides are polar molecules, therefore, their molecules are held together by dipole-dipole attraction. The molecules of H2O are held together by H-bonds. Since the new forces of attraction between water and alkyl halide molecules are weaker than the force of attraction already existing between alkyl halide - alkyl halide molecules and water - water molecules therefore alkyl halides are immiscible (not soluble) in water. Alkyl halide are neither able to form H-bonds with water nor able to break the H-bonding network of water.
