Question

$2C{H}_3\stackrel{\stackrel{O}{\parallel }}{C}O{C}_2{H}_5\stackrel{C_2{H}_{5}ONa}{\to }A$.

Claisen condensation. Which is/are true about $A$?

• A. $A$ forms oxime
• B. $A$ shows tautomerism
• C. $A$ shows iodoform test
• D. All of the above are true

Answer 1

The correct option is D All of the above are true

The compound (A) can form oxime on reaction with $N{H}_{2}OH$. Since the molecule can involve simple proton transfer in an intramolecular fashion, it can undergo tautomerism. (alpha hydrogen)

Iodoform test is used to probe the presence of methyl ketone. Since there is a methyl ketone it shows iodoform test.
