Answer: The following elements have an impact on how soluble alcohols are in water:
(i) Hydrogen bonding – Alcohols are relatively soluble in water and create hydrogen bonds with it. Alcohol is soluble because its hydroxyl group is hydrophilic, or “water-loving,” and forms hydrogen bonds with water.
(ii) Molecular weight – Methanol, ethanol, propanol, butanol, and other alcohols with smaller molecular weights are all miscible with water. Higher molecular weight alcohols are less miscible in water because the hydrophobic (hating water) hydrocarbon component of the molecule grows greater as the weight rises.
