    A typical compound which undergoes both Cannizaro reaction and aldol condensation is

    A)  \[{{(C{{H}_{3}})}_{2}}CH-CHO\]

    B)  \[HCHO\]

    C)  \[{{C}_{6}}{{H}_{5}}CHO\]

    D)  \[C{{H}_{3}}CHO\]

    Correct Answer: A

    Solution :

     Since, 2-methyl propanal contains one\[\alpha -H,\] it undergoes aldol condensation. Surprisingly, it also undergoes cannizaro reaction. \[2{{(C{{H}_{3}})}_{2}}CHCHO\xrightarrow[473\,K]{NaOH}{{(C{{H}_{3}})}_{2}}CHCOONa\]        \[+{{(C{{H}_{3}})}_{2}}CH-C{{H}_{2}}OH\]
