Carbanion
Carbanion
Carbanion (pronounced: /kɑːrˈbænaɪɒn/) is a chemical species, characterized by a carbon atom bearing a negative charge.
Etymology
The term "Carbanion" is derived from the words "carbon" and "anion". The suffix "-anion" is from the Greek word "ἄνιον" (ánion), meaning "up or against", which is used in chemistry to denote a negatively charged ion.
Definition
A Carbanion is a type of carbon molecule that has an extra electron, giving it a negative charge. This charge is usually localized on the carbon atom, making it a very reactive species in organic chemistry. Carbanions are typically formed in reactions involving deprotonation of organic compounds.
Properties
Carbanions are highly reactive due to their negative charge. They are strong nucleophiles, meaning they can donate an electron pair to an electrophile to form a chemical bond. Carbanions can also act as bases, accepting a proton to form a neutral molecule.
