Question

How will you distinguish between ethylamine, diethylamine and triethylamine by using reagent?

Answer 1

Using the Grignard’s reagent, you can distinguish between the ethylamine, diethylamine, and triethylamine.

Grignard’s reagent has the property to react with proton species to give the alkanes.

When you treat the ethylamine and diethylamine with the Grignard’s reagent, it gives you the alkanes as the output.

On the other hand, you cannot get the alkanes while treating the same with triethylamine because of the lack of hydrogen on the nitrogen.
