    Which one of the following does not have \[s{{p}^{2}}\] hybridised carbon?

    A)  Acetone             

    B)  Acetic acid

    C)   Acetonitrile                     

    D)   Acetamide

    Correct Answer: C

    Solution :

    [a]\[\underset{s{{p}^{3}}}{\mathop{C{{H}_{3}}}}\,-\underset{s{{p}^{2}}}{\mathop{\overset{\begin{smallmatrix}  O \\  || \end{smallmatrix}}{\mathop{C}}\,}}\,-\underset{s{{p}^{3}}}{\mathop{C{{H}_{3}}}}\,\]   [b]\[\underset{s{{p}^{3}}}{\mathop{C{{H}_{3}}}}\,-\underset{s{{p}^{2}}}{\mathop{\overset{\begin{smallmatrix}  O \\  || \end{smallmatrix}}{\mathop{C}}\,}}\,-OH\] [c]\[\underset{s{{p}^{3}}}{\mathop{C{{H}_{3}}}}\,-\underset{sp}{\mathop{C}}\,\equiv N\]                        [d]\[\underset{s{{p}^{3}}}{\mathop{C{{H}_{3}}}}\,-\underset{s{{p}^{2}}}{\mathop{\overset{\begin{smallmatrix}  O \\  || \end{smallmatrix}}{\mathop{C}}\,}}\,-N{{H}_{2}}\] Acetonitrile does not contain \[s{{p}^{2}}-\]hybridised carbon.
