Medium
Match the reactant-product combination in Group 1 with the unit process in Group 2: (P) propylene-butanol, (Q) cumene-phenol, (R) butane-butadiene, (S) ethylene dichloride-vinyl chloride — (1) Pyrolysis, (2) Dehydrogenation, (3) Hydroformylation, (4) Peroxidation
- AP-3, Q-2, R-4, S-1
- BP-2, Q-4, R-3, S-1
- CP-1, Q-3, R-2, S-4
- P-3, Q-4, R-2, S-1
Explanation
Propylene is converted to butanol via the oxo (hydroformylation) process (P-3). Cumene is converted to phenol via the cumene (peroxidation) process (Q-4). Butane is dehydrogenated to butadiene (R-2). Ethylene dichloride is thermally cracked (pyrolyzed) to vinyl chloride monomer (S-1).
