Give a chemical test to distinguish between: 2-pentanol and 3-pentanol.

Solution

2-pentanol on oxidation gives methylketone.

This compound has a CH₃C = O group.
Therefore, it will form iodoform (CHI₃) with iodine and alkali on warming. Iodoform is a yellow crystalline substance.

3-pentanol does not show this test.
