    The most reactive compound towards formation of cyanohydrin on treatment with KCN followed by acidification is                                        [GATE 2001]

    A)                 Benzaldehyde  

    B)                 p-Nitrobenzaldehyde

    C)                 Phenyl acetaldehyde    

    D)                 p-Hydroxybenzaldehyde

    Correct Answer: B

    Solution :

                    Due to electron withdrawing nature of \[N{{O}_{2}}\] group, the partial +ve charge on the carbon atom of the \[>C=O\] group in p-nitrobenzaldehyde increases and hence becomes more susceptible to nucleophilic attack by \[C{{N}^{-}}\]ion.
