Q. The correct order of the solubility of different alcohols in water is

A) Ethanol > $n$-propanol > $n$-butyl alcohol
B) $n$-propyl alcohol > ethyl alcohol > $n$-butyl alcohol
C) ethyl alcohol > $n$-butyl alcohol > $n$-propyl alcohol
D) $n$-butyl alcohol > $n$-propyl alcohol > ethyl alcohol
Explanation

(a)
Solubility of alcohols in water decreases as the size of alkyl group increases because tendency to form hydrogen bonding decreases. So, the order of solubility is as
Ethanol > $n$-propanol > $n$-butyl alcohol
