Synthesis (Green Methods / Conventional Methods)

  1. One step synthesis
  •    Aldol condensation (Synthesis of dibenzal propanone)
  • Acetylation (synthesis of acetanilide from aniline)
  • Pechmann Condensation for Coumarin synthesis (Clay catalysed solid state synthesis of 7-hydroxy -4-methyl coumarin)
  • Bromination of phenol

 

  1. Two step synthesis (any three)
  • Benzoin → benzil → benzilic acid
  • Benzophenone → benzpinacol → benzpinacolone
  • Acetanilide → p-bromoacetanilide → p-bromoaniline
  • Acetanilide → p-nitroacetanilide → p-nitroaniline
  • Resorcinol → flouroscein → eosin
  • Pthalic anhydride → pthalimide → anthranilic acid                  

 

Extraction of Organic Compounds from Natural Resources (any three)

  • Isolation of caffeine from tea leaves.
  • Isolation of casein from milk.
  • Isolation of lactose from milk.
