Show Answer

Answer:

Correct Answer: A

Solution:

When benzoic acid reacts with ethyl alcohol in the presence of sulphuric acid ethyl benzoate is formed. This is known as esterification. $ \underset{\text{Benzoic acid}}{\mathop{C_6H_5COOH}}+\underset{\text{Ethyl alcohol}}{\mathop{C_2H_5OH}}\xrightarrow{H_2SO_4} $

$ \underset{\text{Ethyl benzoate}}{\mathop{C_6H_5COOC_2H_5}}+\underset{water}{\mathop{H_2O}} $
