Which of the following is correct ?

Options

A. Alcohols with three or fewer `c's` are water soluble
B. Alcohols with five or more `c's` are insoluble
C. Alcohols with four `c's` are marginally soluble
D. All of these

Answer

D

Explanation

The water solubility of alcohols is attributed to intermolecular `H`-bonding with `H_(2)O`. As the molecular masses of the alcohols increase , their solubility in water decreases , because greater carbon contents makes the alcohols less hydrophilic. Conversely , their solubility in hydrocarbon solvents increases.
