Give simple chemical tests to distinguish between Butanal and butan-2-one.

Text Solution

Verified by Experts

The correct Answer is:
(i) Add a few pieces of sodium metal. Whereas propanol evolves `H_(2)` gas,, diethyl ether does not.
(ii) Add `SOCl_(2)` or `PCl_(5)`; propanol evolves HCl gas at r.t. but diethyl ether does not.
