    The IUPAC name of the compound is \[C{{H}_{3}}-{{[C{{H}_{2}}]}_{5}}-\underset{\begin{align}   & | \\  & C{{H}_{2}} \\  & | \\  & ^{\beta }CHC{{H}_{3}} \\  & | \\  & C{{H}_{2}} \\  & | \\  & C{{H}_{3}} \\ \end{align}}{\mathop{C}}\,H-C{{H}_{2}}-\underset{\begin{align}   & | \\  & ^{\alpha }CHC{{H}_{3}} \\  & | \\  & C{{H}_{2}} \\  & | \\  & {{C}_{2}}{{H}_{5}} \\ \end{align}}{\mathop{C}}\,H-{{[C{{H}_{2}}]}_{_{3}}}-C{{H}_{3}}\]

    A) 7[\[\beta \]methyl butyl], 9 butyl tridecane

    B)        3[\[\beta \]ethyl butyl], 9 ethyl tridecane

    C)        2[\[\beta \]ethyl ethenyl], 8 propyl decane

    D)        None of the above

    Correct Answer: D

    Solution :

    \[\overset{13}{\mathop{C}}\,{{H}_{3}}-{{(C{{H}_{2}})}_{5}}-\underset{\begin{align}   & | \\  & ^{\alpha }C{{H}_{2}} \\  & | \\  & {{H}_{\beta }}-C-{{H}_{3}} \\  & | \\  & C{{H}_{2}} \\  & | \\  & C{{H}_{3}} \\ \end{align}}{\mathop{\overset{7}{\mathop{C}}\,}}\,H-\overset{6}{\mathop{C}}\,{{H}_{2}}-\underset{\begin{align}   & | \\  & H-C-C{{H}_{3}} \\  & | \\  & C{{H}_{2}} \\  & | \\  & C{{H}_{2}} \\  & | \\  & C{{H}_{3}} \\ \end{align}}{\mathop{\overset{5}{\mathop{C}}\,}}\,H-{{[C{{H}_{2}}]}_{_{3}}}-\overset{1}{\mathop{C}}\,{{H}_{3}}\] 5- (\[\alpha \]methyl butyl) 7-(\[\beta -\]methyl butyl) tridecane.
