    The compound in which underlined carbon uses only its \[s{{p}^{3}}\] hybrid orbitals for bond formation is

    A) \[C{{H}_{3}}\underline{C}OOH\]                              

    B)        \[C{{H}_{3}}\underline{C}ON{{H}_{2}}\]               

    C)        \[C{{H}_{3}}\underline{C}{{H}_{2}}OH\]               

    D)        \[C{{H}_{3}}\underline{C}H=C{{H}_{2}}\]

    Correct Answer: C

    Solution :

    \[\underset{s{{p}^{2}}}{\mathop{C{{H}_{3}}-\overset{\begin{smallmatrix}  O \\  |\,| \end{smallmatrix}}{\mathop{C}}\,-OH}}\,\]                         \[\underset{s{{p}^{2}}}{\mathop{C{{H}_{3}}-\overset{\begin{smallmatrix}  O \\  |\,| \end{smallmatrix}}{\mathop{C}}\,-N{{H}_{2}}}}\,\] \[C{{H}_{3}}-\underset{\begin{smallmatrix}  |\,\,\,\,\,s{{p}^{3}} \\  H \end{smallmatrix}}{\overset{\begin{smallmatrix}  H \\  | \end{smallmatrix}}{\mathop{C}}}\,-OH\]                              \[\underset{s{{p}^{2}}}{\mathop{C{{H}_{3}}-\overset{\begin{smallmatrix}  H \\  | \end{smallmatrix}}{\mathop{C}}\,=C{{H}_{2}}}}\,\]
