Updated On: Apr 23, 2026
- A
- B
- C
- D
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
Claisen condensation of ethyl acetate gives ethyl acetoacetate (β-ketoester).
Step 2: Detailed Explanation:
A = CH\(_3\)COCH\(_2\)COOC\(_2\)H\(_5\) (ethyl acetoacetate).
(A) Has C=O group \(\rightarrow\) forms oxime.
(B) Has α-hydrogens \(\rightarrow\) keto-enol tautomerism.
(C) Has CH\(_3\)CO- group (methyl ketone) \(\rightarrow\) iodoform test positive.
Thus, all statements true.
Step 3: Final Answer:
Thus, all of the above are true.
