Question

Alkyl halides are immiscible in water though they are polar because

• A. they react with water to give alcohols
• B. they cannot form hydrogen bonds with water
• C. $C-X$ bond cannot be broken easily
• D. they are stable compounds and are not reactive.

Answer 1

The correct option is B they cannot form hydrogen bonds with water

The molecules of water are held together by hydrogen bonds. As the new force of attraction between water and alkyl halides molecules are weaker than the forces of attraction already existing between alkyl halide- alkyl halide molecules and water - water molecules, they cannot form hydrogen bonds with water.
