The correct Answer is:
To solve the given question, we need to analyze both statements provided and determine their validity based on our understanding of organic chemistry, particularly the reactions involving chloral and the Cannizzaro reaction. ### Step-by-Step Solution: 1. **Understanding Statement 1**: - The statement claims that when chloral (CCl₃CHO) is heated with concentrated potassium hydroxide (KOH), it yields two products: CCl₃COO⁻ and CCl₃CH₂OH. - Chloral is an aldehyde, and when treated with a strong base like KOH, it can undergo a reaction known as the Cannizzaro reaction. However, the expected products from this reaction are different from what is stated. - The Cannizzaro reaction typically produces an alcohol and a carboxylic acid salt from non-enolizable aldehydes. For chloral, the expected products would be chloroform (CHCl₃) and formic acid (HCOOK), not the products mentioned in the statement. **Conclusion for Statement 1**: This statement is **false**. 2. **Understanding Statement 2**: - The second statement discusses the Cannizzaro reaction and claims that the hydride ion transfer is the slowest step. - In the Cannizzaro reaction, the mechanism involves the transfer of a hydride ion (H⁻) from one aldehyde molecule to another, leading to the formation of an alcohol and a carboxylic acid salt. - The hydride transfer is indeed the rate-determining step of this reaction, as it involves the breaking of a bond and is typically slower than other steps in the mechanism. **Conclusion for Statement 2**: This statement is **true**. ### Final Answer: - Statement 1 is false, and Statement 2 is true. Therefore, the correct option is **D**.
