A) 2,2,3,3-tetramethylpentane
B) 2-methylpentane
C) 2,2,3-trimethylpentane
D) 3,3-dimethylpentane
Correct Answer: B
Solution :
\[\underset{\text{2,3,3,3-tetramethylpentane}}{\mathop{{{H}_{3}}C-\overset{\,\,\,\,\,\,C{{H}_{3}}\,C{{H}_{3}}}{\mathop{\overset{|\,\,\,\,\,\,\,\,\,\,\,\,|}{\mathop{\underset{\,\,\,\,\,\,C{{H}_{3}}\,C{{H}_{3}}}{\mathop{\underset{|\,\,\,\,\,\,\,\,\,\,\,|\,}{\mathop{{{H}_{2}}C-C-C-C{{H}_{3}}}}\,}}\,}}\,}}\,}}\,\] \[\underset{\text{isopropyl group 2-methylpentane}}{\mathop{{{H}_{3}}C-{{H}_{2}}C-\overset{\,\,\,\,\,\,\,\,\,C{{H}_{3}}}{\mathop{\overset{\,\,\,\,|}{\mathop{{{H}_{2}}C-HC-C{{H}_{3}}}}\,}}\,}}\,\] \[\underset{\text{2, 2, 3-trimethylpentane}}{\mathop{\underset{\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,C{{H}_{3}}}{\mathop{\underset{\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,|}{\mathop{\overset{\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,C{{H}_{3}}\,C{{H}_{3}}}{\mathop{\overset{\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,|\,\,\,\,\,\,\,\,\,\,|}{\mathop{{{H}_{3}}C-{{H}_{2}}C-HC-C-C{{H}_{3}}}}\,}}\,}}\,}}\,}}\,\]\[\underset{\text{3, 3-dimethylpentane}}{\mathop{\underset{\,\,\,\,\,\,C{{H}_{3}}}{\mathop{\underset{\,|}{\mathop{\overset{\,\,\,\,\,\,\,\,C{{H}_{3}}}{\mathop{\overset{\,\,|}{\mathop{{{H}_{3}}C-{{H}_{2}}C-C-C{{H}_{2}}-C{{H}_{3}}}}\,}}\,}}\,}}\,}}\,\]You need to login to perform this action.
