              In the above given compound x functional group are reduced by LAH (Lithium aluminium hydride) and y functional groups are reduced by SBH (sodium borohydride) respectively. The value of \[(x+y)\] is                                               

    A) \[4\]                       

    B)        \[5\]                       

    C) \[6\]           

    D)        \[7\]

    Correct Answer: C

    Solution :

    [c] (i) LAH reduces aldehyde ketone, acid and ester. (4 groups) (ii) SBH can't reduce ester and acid. Reduces only aldehyde and ketone. (2 groups) So total group \[=4+2=6\]
