What happens when Propanol is heated with concentrate H_2 S O_4 at 180 C temperature

Assertion (A) : NaCl reacts with concentrated H_(2)SO_(4) to give coloured fumes with pungent smell. But on adding MnO_(2) the fumes become greenish - yellow. Reason (R) : MnO_(2) oxidises HCl to chlorine gas which is greenish -yellow. Reason (R) : MnO_(2) oxidises HCI to chlorine gas which greenish- yellow.
