The acid formed when propyl magnesium bromide is treated with CO_2 followed by acid hydrolysis is:
The acid formed when propyl magnesium bromide is treated with CO_2 followed by acid hydrolysis is:
Show Hint
- C_3H_7COOH
- C_2H_5COOH
- CH_3COOH
C_3H_7OH
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Reaction
Propyl magnesium bromide is a Grignard reagent that reacts with carbon dioxide (CO2) to form a carboxylate anion. This anion is then hydrolyzed to form a carboxylic acid. The reaction can be summarized as follows:
RMgBr + CO2 → RCO− + MgBr+
Upon hydrolysis, the carboxylate anion is converted into a carboxylic acid:
RCO− + H2O → RCOOH
Step 2: Conclusion
Thus, the acid formed is propionic acid (C3H7COOH), corresponding to option (A).
Propionic acid is the correct product of this Grignard reaction with CO2.
