Alkenes and alkynes form organic compounds in which the multiple carbon–carbon bond has been replaced by a carbonyl (C=O) group while azo compounds form nitrosamines (N−N=O). The outcome of the reaction depends on the type of multiple bond being oxidized and the work-up conditions. simplify 3 4 2-8 -5 4+2Web22.
