Organic Chemistry – Some Basic Principles and Techniques

13 lessons124 min6 simulations9 practice questions

This chapter is the toolkit for all of organic chemistry: how carbon's tetravalence and hybridisation fix molecular shapes, how organic structures are drawn, classified and named by IUPAC rules, what kinds of isomers exist, and how electrons move during reactions (bond cleavage, reactive intermediates, inductive, resonance, electromeric and hyperconjugation effects). It ends with the practical side: purifying organic compounds and detecting and estimating the elements in them.

Also called: GOC · general organic chemistry · IUPAC nomenclature · inductive and resonance effects
