This is due to the presence of intermolecular hydrogen bonding between alcohol molecules due to the presence of the OH group. The impact of the polar character of the –OH group of alcohol is suppressed when the alkyl group of alcohol or in the case of high molecular mass alcohols increases. When a result, as the molecular size of alcohol rises, its solubility drops.
Explain why low molecular mass alcohols are soluble in water.
