Structural Formulae and Molecular Representations
Organic structures can be written in several formulae and viewed through three-dimensional projections.
Open article →Constitutional Isomerism and Tautomerism
Constitutional isomers share a molecular formula but differ in their sequence of atom connectivity.
Open article →Geometrical and Optical Isomerism
Restricted rotation and chirality create spatially different structures with unchanged connectivity.
Open article →Qualitative Detection of Organic Elements
Organic elements are detected through characteristic oxidation products or sodium-fusion salts.
Open article →Estimation of Carbon, Hydrogen and Oxygen
Measured carbon dioxide and water from complete combustion give carbon and hydrogen mass percentages.
Open article →Gravimetric Estimation of S, Halogens and P
Sulphur, halogens and phosphorus are converted to weighable compounds and calculated by mass fractions.
Open article →Nitrogen Estimation: Dumas and Kjeldahl
Dumas measures corrected nitrogen-gas volume; Kjeldahl measures ammonia captured by standard acid.
Open article →Sublimation and Crystallisation
Sublimation separates a volatile solid; crystallisation exploits solubility differences between hot and cold solvent.
Open article →Distillation, Extraction and Chromatography
Organic mixtures are separated using boiling-point, solvent-distribution or stationary-mobile phase differences.
