Question:
\(\xrightarrow{\mathrm{C_2H_5ONa}} A\), \(A\) is formed by Claisen condensation. Which is/are true about \(A\)?
\(\xrightarrow{\mathrm{C_2H_5ONa}} A\), \(A\) is formed by Claisen condensation. Which is/are true about \(A\)?
Show Hint
Ethyl acetoacetate exhibits keto-enol tautomerism and gives characteristic carbonyl reactions.
Updated On: Apr 23, 2026
- \(A\) forms oxime
- \(A\) shows tautomerism
- \(A\) shows iodoform test
- All of the above are true
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
\[ A = \mathrm{CH_3COCH_2COOC_2H_5} \text{ (Ethyl acetoacetate)} \]
Step 2: Calculation / Simplification}
(a) Contains keto group \(\Rightarrow\) forms oxime with \(\mathrm{NH_2OH}\).
(b) Keto-enol tautomerism due to acidic \(\alpha\)-hydrogens.
(c) \(\mathrm{CH_3CO-}\) group \(\Rightarrow\) positive iodoform test.
All statements are true.
Step 3: Final Answer
\[ \text{All of the above are true} \]
