The structures $ {{(C{{H}_{3}})}_{3}}CBr $ and $ C{{H}_{3}}{{[C{{H}_{2}}]}_{3}}Br $ represent
Rajasthan PETRajasthan PET 2010
Solution:
The structures of the given compounds are as $ {{H}_{3}}\overset{3}{\mathop{C}}\,-\underset{\begin{smallmatrix} | \\ Br \end{smallmatrix}}{\overset{\begin{smallmatrix} C{{H}_{3}} \\ | \end{smallmatrix}}{\mathop{^{2}C}}}\,-\overset{1}{\mathop{C}}\,{{H}_{3}} $ $ \overset{4}{\mathop{C}}\,{{H}_{3}}\overset{3}{\mathop{C}}\,{{H}_{2}}\overset{2}{\mathop{C}}\,{{H}_{2}}\overset{1}{\mathop{C}}\,{{H}_{2}}Br $
Since in these, the chain of carbon atoms and the position of functional group Ye, Br both are different, they exhibit chain as well as position isomerism.
