Expert Solution

Step 1

In a chemical reaction; the substance which involves in conversion is said to be reactant whereas the newly formed substance is called as product. Both reactant and products must be separated by arrow.

Step 2

On the basis of mechanism, chemical reactions can be classified as substitution reactions, addition reaction, elimination reaction and rearrangement reactions.

Step 3

The reaction of carboxylic acid with alcohol results the formation of ester. The reaction is called as esterification reaction and occurs in the presence of dilute acid as catalyst. Ester reacts with ammonia reacts to form amide.
