Isomerization & Aromatization

Isomerization : 

$$\text{CH}_3\text{CH}_2\text{CH}_2\text{CH}_3 \xrightarrow{\text{Anhy. AlCl}_3 / \text{HCl}} \text{CH}_3\text{CH(CH}_3)\text{CH}_3$$

Aromatization :  

$$n\text{-hexane} \xrightarrow{\text{Cr}_2\text{O}_3 / \text{V}_2\text{O}_5 / \text{Mo}_2\text{O}_3, \, 773\text{ K}, \, 10\text{-}20\text{ atm}} \text{Benzene} + 4\text{H}_2$$
