Question

Arrange the following compounds in the decreasing order of their solubility in water:

i. n-Butane

ii. Butan-1-ol

iii. Butan-1-amine

पर्याय

• ii > iii > i

• ii > i > iii

• iii > ii > i

• i > iii > ii

Answer 1

ii > iii > i

Explanation:

In amines, the N - H bonds are less polar than the O - H bonds in alcohols. Water solubilities of alcohols, amines, and alkanes of similar molar mass decrease in the following order:

alcohols > amines > alkanes
