3 Odour The ability to detect and remember an odour is very valuable in qualitative organic chemistry. 0-41 SYSTEMATIC IDENTIFICATION OF ORGANIC COMPOUNDS Many types of organic compounds have characteristic odours. It is not possible to describe odours in a precise manner, but the student should become familiar with the odours of common compounds.
