Question

What happens when ethanamine is treated with excess of chloroethane?

Answer 1

Answer:

The specific action of an enzyme with a single substrate can be explained using a Lock and Key analogy first postulated in 1894 by Emil Fischer. In this analogy, the lock is the enzyme and the key is the substrate. Only the correctly sized key (substrate) fits into the key hole (active site) of the lock (enzyme).

Answer 2

When ethanamine is treated with excess of chloroethane then tetraethylammoniumchloride is formed.

Following things happen when ethanamine is treated with excess of choloethane :

1. When Ammonia Reacts with Chloroethane :

• When ammonia and chloroethane react with each other then they form ethanamine.

    2. When Excess Ethanamine Reacts with Chloroethane :

• When excess ethanamine is reacted with chloroethane then secondary amine is formed. This further led to formation of tertiary amines.

    3. When Ethylamine is treated with Excess of Chloroethane :

• When ethanamine is treated with excess chloroethane then quaternary ammonium salt is formed. This reaction is also known as Hofmann ammonolysis of alkyl halides (fluorine, chlorine, bromine, etc.)
• (C₂H₅)₃N + C₂H₅Cl (in excess) → Tetraethylammonium chloride (Quaternary ammonium salt).

Hence, when ethanamine is treated with excess chloroethane then tetraethylammonium chloride is formed.
