How are branched alkanes formed from normal alkanes ?

Explanation

Isomerisation is a chemical process by which a compound is transformed into any its isomeric forms. Normal alkanes can be converted into branched alkanes in the presence of `AlCl_(3)` and `HCl` at `298K`.
`CH_(3)-CH_(2)-CH_(2)-CH_(3)overset(AlCl_(3)//HCl)underset(298K)(to)underset(CH_(3))overset(CH_(3)-CH-CH_(3))(|)`
This process is of great industrial importance. The quality of gasoline is improved by isomersing its componets.
