Difference Between Carbocation and Carbanion

Carbocation

Carbanion

It is a positively charged carbon cation.It is a negatively charged carbon anion.
The carbocation has six valence electrons and three covalent bonds.The carbanion has eight valence electrons and three covalent bonds.
The carbon atom with a positive charge is sp2 hybridized.The carbon atom with a negative charge is sp3 hybridized.
An empty p-orbital perpendicular to the plane of substituents is present.A p-orbital with an electron pair perpendicular to the plane of substituents is present.
The geometry of carbocation is trigonal planar. The geometry of carbanion is trigonal pyramidal.
The angle between the substituents is 120o.The angle between the substituents is less than 109.5o.
It acts as an electron-acceptor in reactions.It acts as an electron donor in reactions.
Electron donating substituents stabilize the carbocations.Electron withdrawing substituents stabilize anions.

The order of stability of alkyl carbocations is-

 Methyl carbocation <10 <20 <30

The order of stability of carbanions is-
