Question

Write chemical test to distinguish between propanol and propanone

Answer 1

• Tollens silver mirror test is used to distinguish propanol and propanone.

It gives a silver mirror for aldehyde.

• Haloform test can also be very helpful in distinguishing propanol and propanone.

In the haloform test both of them will be treated with iodine along with KOH. The resultant will give iodoform only in the case of ethanal.

Answer 2

HEY!!

______________________________

✔Use the haloform test. Treat with iodine in KOH. Iodoform will be formed only in the case of ethanal.

✔Use the Tollen's mirror test. Treat with warm ammonical solution of silver chloride. Only propanal will give the silver mirror.

✔Use a solution of Ceric ammonium nitrate. The ethanol will give a red precipitate.
