Carbanions and Carbocations

What Are Carbanions?

They are generated by heterolytically cleaving a group attached to carbon without removing the bonded electrons. This makes the carbon have a pair of electrons, thereby imparting a negative charge on the carbon. CH₃^– is isoelectronic with NH₃, and it is sp³ hybridized, and the shape is pyramidal owing to the presence of a lone pair of electrons.
