Hexane yields different products under different conditions. Provide three such reactions.

(N/A) Hexane undergoes different chemical reactions depending on the conditions provided:
$(a)$ Aromatization: $n$-Hexane,when heated to $773 \ K$ under $10-20 \ atm$ pressure in the presence of $Cr_2O_3/V_2O_5/Mo_2O_3$ catalysts,undergoes cyclization and dehydrogenation to form benzene.
$(b)$ Pyrolysis (Thermal Cracking): When $C_6H_{14}$ is heated to $773 \ K$,it undergoes thermal decomposition to produce a mixture of smaller hydrocarbons and hydrogen gas,such as:
$(i)$ $C_6H_{14} \rightarrow C_6H_{12} + H_2$
(ii) $C_6H_{14} \rightarrow C_4H_8 + C_2H_6$
(iii) $C_6H_{14} \rightarrow C_3H_6 + C_2H_4 + CH_4$ (Note: The original image showed $CH_3$ radical,which is corrected to $CH_4$ for balanced stoichiometry).
$(c)$ Isomerization: $n$-Hexane,when heated with anhydrous $AlCl_3$ and $HCl$,undergoes isomerization to form branched-chain alkanes like $2$-methylpentane and $3$-methylpentane.
