The correct Answer is:
To analyze the assertion and reason provided in the question, we will follow these steps: ### Step 1: Understand the Assertion The assertion states that in the Hunsdicker reaction, alkyl chlorides are formed in poor yield. ### Step 2: Understand the Reason The reason states that in this reaction, a carbanion is formed as an intermediate. ### Step 3: Analyze the Hunsdicker Reaction The Hunsdicker reaction involves the reaction of silver salts of carboxylic acids with halogens (like Cl2, Br2) in the presence of carbon tetrachloride (CCl4). ### Step 4: Identify the Mechanism In this reaction, free radicals are generated rather than carbanions. The reaction proceeds through the formation of free radicals which then combine to form alkyl halides and release carbon dioxide (CO2). ### Step 5: Evaluate the Yield of Alkyl Chlorides The yield of alkyl chlorides is poor because the bond between chlorine and carbon is strong, making it less favorable for the reaction to proceed compared to bromine, where the bond is weaker and more easily broken. This results in a lower yield of the desired product when chlorine is used. ### Step 6: Conclusion on Assertion and Reason - The assertion is **true**: Alkyl chlorides are formed in poor yield in the Hunsdicker reaction. - The reason is **false**: Carbanions are not formed; free radicals are the intermediates in this reaction. ### Final Answer The assertion is true, but the reason is false.
