    Which of the following compound will not give Cannizzaros reaction?                              

    A)  \[{{(Me)}_{3}}CCHO\]     

    B)  \[HCHO\]           

    C)  \[C{{H}_{3}}CHO\]   

    D)  \[{{C}_{6}}{{H}_{5}}CHO.\]

    Correct Answer: C

    Solution :

    Cannizaro reaction is given by those aldehydes and ketones which do not contain any a-hydrogens \[\underset{Me}{\overset{Me}{\mathop{\underset{|}{\overset{|}{\mathop{Me-C-CHO}}}\,}}}\,,\,\,\,\,\,\,\,\,C{{H}_{2}}=O,\,\,\,{{C}_{6}}{{H}_{5}}-CHO\] No \[\alpha \]-hydrogen atom is present.
