Learning Objective: To learn about the structure, type, and nature of the carbanion intermediate part of organic chemistry reactions.
Skill Level - Intermediate
Prerequisites:
Hybridization (Chapter - Covalent Bond)
Chapter: Reactive Intermediates
Sub-topic: Carbanion
Author's Note: Carbanion is peculiar in having a complete octet yet trivalent, sp3 hybridised yet it does not have a tetrahedral geometry. Central carbon has eight electrons, yet it contains a negative charge and much more.
Carbanion's electron excess is useful for the carbon to fulfill its tetravalency by undergoing bond formation reactions in organic chemistry. In this section, I start with the structure, nature, and types of carbanions, which molecules form carbanions, and the key differences between a normal alkyl carbon and a carbanion.
Carbanion - Introduction, Nature, and Types
A negatively charged, trivalent carbon atom with eight electrons in its valence shell is called a carbanion, a reactive intermediate in many reactions.
With three bonds and an excess of one unshared pair of electrons, the carbanions donate these excess electrons to electron-deficient centres; therefore, it acts as a base and nucleophile in reactions.

Difference Between a Normal, Alkyl Carbon and Carbanion
A carbon atom can form four equal energy bonds using its valence electrons through the hybridization step so that the covalently bonded carbon has a complete octet. Such an alkyl carbon...
In carbanion, one of the....
Types of Carbanions
Based on the number of alkyl substituents on the carbon, carbanions are of three types....
