Unit I: 

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
  • Pthalicanhydride → pthalimide → anthranilicacid

 

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.
  • Isolation of nicotine dipicrate from tobacco.

 

Spectroscopy

Identification of organic compounds (with emphasis on isomeric studies and calculation of % ratio of tautomers) by the spectral analysis.

 

Spectrophotometric Estimations (any three)

  • Protein
  • Carbohydrate
  • Cholesterol
  • Phosphate
  • Ascorbic acid
