Alcohols are comparatively more soluble ...

Alcohols are comparatively more soluble in water than hydrocarbons of comparable melecular masses. Explain this fact.

Text Solution

Verified by Experts

Alcohols can form H-bonds with water with water and break the H-bonds already existing between water molecules. Therefore, they are soluble in water.

On the other hand, hydrocarbons cannot form H-bonds with water and hence are incoluble in water.
