Carbanions
The carbon species carrying a negative charge on carbon atoms is called carbanion. Carbon in carbanion is generally sp3 hybridised and its structure is distorted tetrahedron as shown in the figure given below. Carbanions are also unstable and reactive species.
The stability order of carbanions:-
1. The stability of carbanions is influenced by resonance, inductive effect and s-character of orbitals. The group having +I effect decreases the stability while groups having -I effect increase the stability of carbanions.
2. The groups like -NO2, -CN, -COOC2H5, halogens and C6H5-(electron attracting) increase the stability of carbanions.
