C_(6)H_(6) + C_(2)H_(5)Cl overset(AlCl_(3))rarr X underset((CH_(3)COO)_(2)Mn)overset("Oxygen")rarr Y overset(H_(2)Cr_(2)O_(7))rarr Z Discuss the sequence and name the compounds X, Y and Z |
| Answer» SOLUTION :Compound X is ethylbenzene, `C_(6)H_(5)C_(2)H_(5)`. The reaction is called Friedel-Crafts ethylation. Y is acetophenone, `C_(6)H_(5)COCH_(3)`. Oxidation of ethyl benzene at 400K in the presence of MANGANESE acetate CATALYST gives acetophenone. Z is BENZOIC acid, `C_(6)H_(5)COOH`. Aromatic ketones give carboxylic acids in the presence of powerful oxidants. | |
