Identify CORRECT decreasing order of solubilities of alcohols, alkanes and amines in water having comparable molar mass.
  1. Alcohol $>$ amine $>$ alkane
  2. Alkane $>$ amine $>$ alcohol
  3. Amine $>$ alcohol $>$ alkane
  4. Alkane $>$ alcohol $>$ amine

Solution

Amines are less soluble in water as compared to alcohols having comparable molar mass, since $\mathrm{N}-\mathrm{H}$ bonds in amines are less polar than $\mathrm{O}-\mathrm{H}$ bond in alcohol.
