MCQ
Which pair represents chain isomer
- A$C{H_3}CHC{l_2}$ and $ClC{H_2}C{H_2}Cl$
- B$n-$propyl alcohol and isopropyl alcohol
- C$2-$methyl$-1$ propanol and $2-$Methyl$-2$ propanol
- ✓$2-$methyl butane and neopentane
✓
Answer
Correct option: D.
$2-$methyl butane and neopentane
d
$\begin{matrix} C{{H}_{3}}-CH-C{{H}_{2}}-C{{H}_{3}} \\ |\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, \\ C{{H}_{3}}\,\,\,\,\,\,\,\,\,\,\, \\ \end{matrix}$
$\begin{matrix} C{{H}_{3}}-CH-C{{H}_{2}}-C{{H}_{3}} \\ |\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, \\ C{{H}_{3}}\,\,\,\,\,\,\,\,\,\,\, \\ \end{matrix}$
$2$-methyl butane
$\begin{matrix} C{{H}_{3}} \\ | \\ C{{H}_{3}}-C-C{{H}_{3}} \\ | \\ C{{H}_{3}} \\ \end{matrix}$
neo pentane
Since, they have same molecular formula but they differ in branching. So they are chain isomer.
