Question

What is the difference between carbocation and carbanion?

Answer 1

Carbocation	Carbanion
The ion which contains the positive charge on Carbon atom is called Carbocation.	The ion which contains the negative charge on the Carbon atom is called Carbanion.
The hybridization of carbocation is ${\mathrm{sp}}^2$.	The hybridization of carbanion is ${\mathrm{sp}}^3$.
The geometry of Carbon in carbocation is trigonal planar.	The geometry of Carbon in carbanion is pyramidal.
They are paramagnetic in nature	They are diamagnetic in nature.
In any chemical reaction, they act as electrophiles.	In any chemical reaction, they act as nucleophile.
Example: Methanium ${\mathrm{CH}}_5^{+}$, Ethanium ${\mathrm{C}}_2{\mathrm{H}}_7^{+}$, etc.	Example: Aryl, Vinyl, Acetylide, etc.
