Question

X reacts with chlorine (\({Cl}_2\)) under boiling conditions to form Benzotrichloride, which further reacts with \(H_3O^+\) to form Y. Identify X and Y.
\[ \textbf{X} \xrightarrow{{Cl}_2, \text{Boiling}} \textbf{Benzotrichloride} \xrightarrow{H_3O^+} \textbf{Y} \]

• A. Benzene, Benzaldehyde
• B. Toluene, Benzaldehyde
• C. Toluene, Benzoic Acid
• D. Benzene, Benzoic Acid

Hint:

Benzotrichloride hydrolysis in the presence of \( H_3O^+ \) leads to the formation of Benzoic Acid. This reaction is used in the industrial synthesis of benzoic acid from toluene.
 

Answer 1

The Correct Option is C

Step 1: Identifying the reaction mechanism 
Toluene (\(C_6H_5CH_3\)) undergoes chlorination under boiling conditions, leading to the formation of Benzotrichloride (\(C_6H_5CCl_3\)). 
Step 2: Conversion to Benzoic Acid 
Benzotrichloride (\(C_6H_5CCl_3\)) undergoes acidic hydrolysis (\(H_3O^+\)), resulting in Benzoic Acid (\(C_6H_5COOH\)). 
Conclusion: Thus, \(X\) is Toluene and \(Y\) is Benzoic Acid.
