What happens when :

A. 2, 4, 6 – trinitrochlorobenzene is treated with warm water.

B. 2-chlorobutane is treated with alcoholic KOH.

C. Ethyl chloride is treated with Na metal in presence of dry ether.

Write the equation involved in the above reactions.

A)When 2,4,6-trinitrochlorobenzene react with the warm water to give 2,4,6-trinitrophenol as a product.

The more the number of electron-withdrawing groups present at the ortho- and para- positions, the faster is the nucleophilic substitution reaction.

Thus, the reaction of 2,4,6-trinitrochlorobenzene with warm water gives 2,4,6-trinitrophenol.

The reaction involved is as follows:

B)

According to Zaitsev rule, during elimination,the most substituted product will be the most stable, and therefore the most favored.

C) This following reaction is known as wurtz reaction
