How Organic Reactions Occur:Mechanisms Radical reaction Process that involves symmetrical bond breaking and bond making Radical (free radical) A neutral chemical species that contains an odd number of electrons and has a single,unpaired electron in one of its orbitals Polar reaction Process that involves unsymmetrical bond breaking and bond making Involve species that have an even number of electrons (have only electron pairs in their orbitals) Common in both organic and biological chemistryRadical reaction ▪ Process that involves symmetrical bond breaking and bond making ▪ Radical (free radical) ▪ A neutral chemical species that contains an odd number of electrons and has a single, unpaired electron in one of its orbitals Polar reaction ▪ Process that involves unsymmetrical bond breaking and bond making ▪ Involve species that have an even number of electrons (have only electron pairs in their orbitals) ▪ Common in both organic and biological chemistry How Organic Reactions Occur: Mechanisms
