JEE Advanced levelSingle correct optionDifficulty 3 of 3co210

1,4-Dimethylbenzene is heated with excess alkaline and acidified. The product is refluxed with excess and then treated with excess . The final organic product is

  1. Abenzene-1,4-dicarbonitrile
  2. Bbenzene-1,4-dicarboxamide
  3. C4-methylbenzamide
  4. D4-carbamoylbenzoic acid

Answer: B

Both benzylic methyl groups are oxidised, giving benzene-1,4-dicarboxylic acid. converts both groups to , and excess ammonia converts both to , giving benzene-1,4-dicarboxamide.
