Which from following is a correct decreasing order of water solubilities of organic compounds?

Step-by-step solution

Decreasing order of water solubility: Alcohols > Amines > Alkanes Water solubility depends on the ability to form hydrogen bonds. Alcohols contain a polar O-H group, forming strong hydrogen bonds with water due to oxygen's high electronegativity ( O 3.44 ). Amines with N-H groups form moderately strong hydrogen bonds, though nitrogen's lower electronegativity ( N 3.04 ) results in weaker bonding than alcohols. Alkanes are nonpolar and cannot form hydrogen bonds, exhibiting only London dispersion forces.
