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

    A) \[HCOOH\]

    B) \[N{{H}_{2}}CON{{H}_{2}}\]

    C)  \[{{(C{{H}_{3}})}_{3}}COH\]

    D) \[C{{H}_{3}}CHO\]

    Correct Answer: C

    Solution :

     \[\underset{s{{p}^{3}}}{\mathop{C{{H}_{3}}}}\,-\underset{s{{p}^{3}}}{\overset{s{{p}^{3}}}{\mathop{\underset{C{{H}_{3}}}{\overset{C{{H}_{3}}}{\mathop{\underset{|}{\overset{|}{\mathop{C}}}\,}}}\,}}}\,-OH\] In the above compound all bonds are or bond and hence, carbon atom uses only \[s{{p}^{3}}-\]hybrid orbitals for bond formation.
