CLASSIFICATION OF ELECTRON SINKS

Classification of a given structure into its most appropriate generic class relies on your ability to recognize electron-deficient species, leaving groups, and polarized multiple bonds. Figure 6.2 shows a flowchart for classification of electron sinks. 

Figure A.l Flowcharts for the classification of electron sources and sinks.

Electron sinks have a full, partial, or inducible plus charge on the atom that gets attacked by the electron source. The larger the partial plus is, the better the electron sink can attract a negatively charged electron source. Table 6.2 repeated below gives the common electron sinks, and Figure A.l shows a flowchart of the classification process.
