In organic chemistry, a carbanion is an anion in which carbon is trivalent (forms three bonds) and bears a formal negative charge (in at least one significant resonance form). Formally, a carbanion is the conjugate base of a carbon acid: where B stands for the base. The carbanions formed from deprotonation of … Zobacz więcej Absent π delocalization, the negative charge of a carbanion is localized in an sp hybridized orbital on carbon as a lone pair. As a consequence, localized alkyl, alkenyl/aryl, and alkynyl carbanions assume … Zobacz więcej With the molecular geometry for a carbanion described as a trigonal pyramid the question is whether or not carbanions can display chirality, because if the activation … Zobacz więcej A carbanionic structure first made an appearance in the reaction mechanism for the benzoin condensation as correctly proposed by … Zobacz więcej Carbanions are typically nucleophilic and basic. The basicity and nucleophilicity of carbanions are determined by the substituents on … Zobacz więcej Any compound containing hydrogen can, in principle, undergo deprotonation to form its conjugate base.
