The correct Answer is:
To analyze the statements provided, we will break down each statement and evaluate their validity step by step. ### Step 1: Evaluate Statement 1 **Statement 1:** Acetoacetic ester `(CH₃COCH₂COOC₂H₅)` contains `CH₃CO` group but does not give iodoform test. - **Explanation:** The iodoform test is a qualitative test for the presence of a methyl ketone or a compound that can be oxidized to a methyl ketone. The presence of the `CH₃CO` (acetyl) group is necessary for a compound to give a positive iodoform test. However, acetoacetic ester is an ester and not a simple ketone. The presence of the ester functional group (`COOC₂H₅`) means that it does not have the necessary structure to undergo the iodoform reaction. Therefore, acetoacetic ester does not give a positive iodoform test despite containing the `CH₃CO` group. **Conclusion:** Statement 1 is **True**. ### Step 2: Evaluate Statement 2 **Statement 2:** The H-atoms of the `CH₃` group are more acidic than those of the `CH₂` group. - **Explanation:** In acetoacetic ester, the `CH₃` group is part of a ketone structure, while the `CH₂` group is adjacent to the carbonyl group. The acidity of hydrogen atoms is influenced by the stability of the resulting anion after deprotonation. The `CH₃` group has hydrogen atoms that are less acidic than the `CH₂` group because the `CH₂` group is adjacent to the carbonyl, which can stabilize the negative charge through resonance when the hydrogen is removed. Therefore, the hydrogen atoms of the `CH₂` group are more acidic than those of the `CH₃` group. **Conclusion:** Statement 2 is **False**. ### Final Conclusion - Statement 1 is True. - Statement 2 is False.
