Marking-scheme solution
Structural isomers of butane
$\displaystyle / \mathrm{CH}_{3}-\mathrm{CH}_{2}-\mathrm{CH}_{2}-\mathrm{CH}_{3}$
$\displaystyle / \mathrm{CH}_{3}-\underset{\mathrm{CH}_{3}}{\mathrm{CH}-\mathrm{CH}_{3}}$
$\displaystyle / \mathrm{CH}_{3}-\mathrm{CH}_{2}-\mathrm{CH}_{2}-\mathrm{CH}_{3}$
$\displaystyle / \mathrm{CH}_{3}-\underset{\mathrm{CH}_{3}}{\mathrm{CH}-\mathrm{CH}_{3}}$More from Carbon and its Compounds
