Make up the reaction equation: C6H14 → cyclohexane; C6H14 → C6H6 → C6H5NO2

1 chain:

1) C6H14 = C6H12 + H2 (during the dehydrocyclization of hexane, cyclohexane and hydrogen are formed).

2 chain:

1) C6H14 = C6H6 + 4H2 (when heated and catalyzed from hexane, benzene and hydrogen are formed);

2) C6H6 + HNO3 = C6H5NO2 + H2O (when benzene reacts with nitric acid, nitrobenzene and water are formed, nitration reaction).
