Question

give a chemical test to distinguish between methanol and dimethyl etheer​

Answer 1

Answer:

This can be easily done with a small piece of sodium.

Alcohols like methanol and ethanol readily liberates bubbles of hydrogen gas with metallic sodium at room temperature, as they contain active hydrogen in the hydroxyl group.

CH3OH + Na = CH3ONa + H2

Pure ether does not react with sodium due to absence of polar hydrogen in its composition.

Answer 2

Answer:

Methanol on reaction with Na metal will yield H2 gas where as Dimethyl ether do not evolve H2 gas with Na Metal.

CH3OH −→−−−Na metal H2(g)CH3OCH3−→−−−Na metalNo observation

Hope this helps,
