Purification and Characterisation of Organic Compounds

An Organic Chemistry unit for JEE Main 2027 (typically 1-2% of the paper). It covers the purification of organic compounds (crystallisation, sublimation, distillation, differential extraction and chromatography), qualitative analysis (detection of nitrogen, sulphur and halogens), and quantitative analysis (estimation of carbon, hydrogen, nitrogen, halogens, sulphur and phosphorus) leading to empirical and molecular formula determination.
