      The above reaction is called

    A)  Aldol reaction

    B)  Cannizzaro reaction

    C)  Schmidt reaction

    D)  Tischenko reaction

    Correct Answer: A

    Solution :

     \[\underset{acetone}{\mathop{C{{H}_{3}}-\underset{\begin{smallmatrix}  || \\  O \end{smallmatrix}}{\overset{\begin{smallmatrix}  C{{H}_{3}} \\  | \end{smallmatrix}}{\mathop{C}}}\,}}\,+\underset{acetone}{\mathop{H-C{{H}_{2}}-\overset{\begin{smallmatrix}  O \\  || \end{smallmatrix}}{\mathop{C}}\,-C{{H}_{3}}}}\,\xrightarrow[{}]{NaOH}\] \[\underset{aldol}{\mathop{C{{H}_{3}}-\underset{\begin{smallmatrix}  | \\  OH \end{smallmatrix}}{\overset{\begin{smallmatrix}  C{{H}_{3}} \\  | \end{smallmatrix}}{\mathop{C}}}\,}}\,-C{{H}_{2}}-\overset{\begin{smallmatrix}  O \\  || \end{smallmatrix}}{\mathop{C}}\,-C{{H}_{3}}\] This is aldol condensation reaction.
