    Pentane has the molecular formula \[{{C}_{5}}{{H}_{12}}\]. It has

    A)  5 covalent bonds    

    B)  12 covalent bonds

    C)  16 covalent bonds           

    D)  17 covalent bonds

    Correct Answer: C

    Solution :

    \[\text{H}-\underset{\begin{smallmatrix}  \text{ }\!\!|\!\!\text{ } \\  \text{H} \end{smallmatrix}}{\overset{\begin{smallmatrix}  \text{H} \\  \text{ }\!\!|\!\!\text{ } \end{smallmatrix}}{\mathop{\text{C}}}}\,-\underset{\begin{smallmatrix}  \text{ }\!\!|\!\!\text{ } \\  \text{H} \end{smallmatrix}}{\overset{\begin{smallmatrix}  \text{H} \\  \text{ }\!\!|\!\!\text{ } \end{smallmatrix}}{\mathop{\text{C}}}}\,-\underset{\begin{smallmatrix}  \text{ }\!\!|\!\!\text{ } \\  \text{H} \end{smallmatrix}}{\overset{\begin{smallmatrix}  \text{H} \\  \text{ }\!\!|\!\!\text{ } \end{smallmatrix}}{\mathop{\text{C}}}}\,-\underset{\text{pentane}}{\mathop{\underset{\begin{smallmatrix}  \text{ }\!\!|\!\!\text{ } \\  \text{H} \end{smallmatrix}}{\overset{\begin{smallmatrix}  \text{H} \\  \text{ }\!\!|\!\!\text{ } \end{smallmatrix}}{\mathop{\text{C}}}}\,-\underset{\begin{smallmatrix}  \text{ }\!\!|\!\!\text{ } \\  \text{H} \end{smallmatrix}}{\overset{\begin{smallmatrix}  \text{H} \\  \text{ }\!\!|\!\!\text{ } \end{smallmatrix}}{\mathop{\text{C}}}}\,-\text{H}}}\,\]covalent bonds.
