A) A forms oxime
B) A shows tautomerism
C) A shows iodoform test
D) All of the above are true
Correct Answer: D
Solution :
\[C{{H}_{3}}\overset{\begin{smallmatrix} O \\ || \end{smallmatrix}}{\mathop{C}}\,O{{C}_{2}}{{H}_{5}}+HC{{H}_{2}}\overset{\begin{smallmatrix} O \\ || \end{smallmatrix}}{\mathop{C}}\,O{{C}_{2}}{{H}_{5}}\] \[\xrightarrow{{{C}_{2}}{{H}_{5}}ONa}C{{H}_{3}}\overset{\begin{smallmatrix} O \\ || \end{smallmatrix}}{\mathop{C}}\,\underset{(A)\,\,Keto\,\,ester}{\mathop{C{{H}_{2}}}}\,\overset{\begin{smallmatrix} O \\ || \end{smallmatrix}}{\mathop{C}}\,O{{C}_{2}}{{H}_{5}}\] (b) A forms oxime due to keto group (c) A shows tautomerism (d)A shows iodoform test due to\[C{{H}_{3}}\overset{\begin{smallmatrix} O \\ || \end{smallmatrix}}{\mathop{C}}\,-\]
