Answer:
Solubility
of alcohols in water depends upon the following two factors :
(i) Hydrogen bonding. O?H group in alcohol being polar forms H-bonds with
Greater the extent of H-bonding,
higher is the solubility. For alcohols having comparable molecular masses,
solubility increases as the number of OH groups increases, i.e.,
(ii) Size of the alkyl/aryl group. Higher the hydrocarbon part, lower is
the extent of H-bonding and hence lower is the solubility. For example,
solubility decreases in the order :
