Alcohols are comparatively more soluble ...

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

Text Solution

Verified by Experts

Alcohols can formH -bonds with wạter and break the H- bonds already existing between, water molecules. Therefore they are soluble in water. Figure On the other hand. hydrocarbons cannot form HDonds with water and hence are insoluble in water.

o-Nitrophenol is less soluble in water than p - and m - nitrophenols because

o-Nitrophenol is more volatile in steam than those of m - and p - isomers

o-nitrophenol shows intramolecular H-bonding

o-nitrophenol shows intermolecular H-bonding

melting point of o-nitrophenol is lower than those of m - and p - isomers
