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