Basic techniques Involved in Synthetic Organic Chemistry

  • Different types of glasswares.
  • Filtration.
  • Distillation (distillation at atmospheric pressure, steam distillation, fractional distillation and distillation at reduced pressure).
  • Recrystallization and melting point correction.
  • Use of decolorizing carbon.
  • Thin layer chromatography.

Qualitative Analysis

Separation, purification and identification of components of a mixture of two organic compounds (one liquid and one solid or two solids) using TLC for checking the purity of separated compounds.

Quantitative Analysis

  • Determination of the percentage and number of hydroxyl groups in an organic compound by acetylation method.
  • Estimation of amines/phenols using bromate bromide solution.
  • Determination of iodine number and saponification value of an oil sample.

Demonstration Exercise

  • Estimation of sulphur by messenger or fusion method.
  • Estimation of nitrogen by Kjeldahl’s method.
