Absent π delocalization, the negative charge of a carbanion is localized in an spx hybridized orbital on carbon as a lone pair. As a consequence, localized alkyl, alkenyl/aryl, and alkynyl carbanions assume trigonal pyramidal, bent, and linear geometries, respectively. By Bent's rule, placement of the … Visa mer Carbanions are typically nucleophilicand basic. The basicity and nucleophilicity of carbanions are determined by the substituents on carbon.
