    The structural formula of benzylphenyl ketone is:

    A)  \[{{C}_{6}}{{H}_{5}}CO{{C}_{6}}{{H}_{5}}\]

    B)  \[{{C}_{6}}{{H}_{5}}CO\cdot CO{{C}_{6}}{{H}_{5}}\]

    C)  \[{{C}_{6}}{{H}_{5}}C{{H}_{2}}COC{{H}_{2}}{{C}_{6}}{{H}_{5}}\]

    D)  \[{{C}_{6}}{{H}_{5}}C{{H}_{2}}CO{{C}_{6}}{{H}_{5}}\]

    Correct Answer: D

    Solution :

    The benzyl group is \[{{C}_{6}}{{H}_{5}}C{{H}_{2}}\] and phenyl group is \[{{C}_{6}}{{H}_{5}}\]. Hence, benzylphenyl ketone is \[{{C}_{6}}{{H}_{5}}C{{H}_{2}}--\,\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,--\,{{C}_{6}}{{H}_{5}}\]
