Ethanol is miscible in water, while 1-pentanol has a solubility of just 2.2g/100 mL because solubility in water decreases with increasing alcohol size.

Question

Quizplus · Accepted Answer

Ethanol is fully miscible in water due to its small size and ability to form hydrogen bonds with water. As the carbon chain length increases in alcohols like 1-pentanol, their hydrophobic character increases, leading to decreased solubility in water.
