    A)      \[>C=O\]

    B) \[-C\equiv N\]

    C)      \[>C=S\]

    D) All of the above

    Correct Answer: D

    Solution :

               Grignard reagent gives addition reactions with compounds containing    x\[C=O,\,-C\equiv N\] and    \[C=S\] groups.                                                                                                              \[>\overset{R}{\mathop{\overset{|}{\mathop{C}}\,}}\,-OH+Mg<\overset{OH}{\mathop{\underset{X}{\mathop{{}}}\,}}\,\]                                                                                                 \[-\overset{R}{\mathop{\overset{|}{\mathop{C}}\,}}\,=O+N{{H}_{3}}+Mg<\overset{OH}{\mathop{\underset{X\,\,}{\mathop{{}}}\,}}\,\]                                               \[>\overset{R}{\mathop{\overset{|}{\mathop{C}}\,}}\,-SH+Mg<\overset{OH}{\mathop{\underset{X\,}{\mathop{{}}}\,}}\,\]
