Question
How can we obtain isobutane from n-butane?
✓

Answer

Isobutane can be obtained by heating n-butane with $\mathrm{AlCl}_3$ by isomerisation reaction. $\text{CH}_3-\text{CH}_2-\text{CH}_2-\text{CH}_3\xrightarrow[\text{heat}]{\text{AlCl}_3}\text{CH}_3-\text{CH}-\text{CH}_3\\\ \ \ \ \ \ \ \ \ \ _\text{n-Butane} \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ |\\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \text{CH}_3\\\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ _\text{Isobutane}$
