Question

HOOC–(CH₂)₄–COOH + 2C₂H₅OH \(\xrightarrow{H_2SO_4}\) C₂H₅COOC–CH₂–COOC₂H₅
The purpose of using toluene here is

• A. to make both substances (acid and alcohol) miscible
• B. that the product is insoluble in toluene
• C. that the reactants are insoluble in water
• D. because of the formation of low boiling azeotrope

Hint:

In esterification reactions, using an appropriate solvent like toluene can improve reaction efficiency.

Answer 1

The Correct Option is A

Step 1: Purpose of toluene in esterification.
Toluene is used as a solvent in esterification reactions because it helps dissolve both the alcohol and the acid, making the reaction more efficient.

Step 2: Conclusion.
Thus, the correct answer is option (A).

Final Answer: \[ \boxed{\text{(A) to make both substances (acid and alcohol) miscible}} \]
