Reaction Intermediates

Short lived fragments that are known as reaction intermediates result from homolytic and heterolytic bond fission. The significant reaction substances are carbanions,carbocations, benzyne, carbenes, free radicals, and nitrenes.

Table

Characteristic	Free radical	Carbocation	Carbanion	Carbene
Nature	Neutral having odd electron	Positive charge on C	Negative charge on C	Neutral, divalent with 2 unshared electrons
Hybridisation	sp²	sp²	sp³ (non-conjugated) sp² (Conjugated)	(i) sp² (singlet) (ii) sp (triplet)
Structure	Planar	Planar	Pyramidal/Planar	(i) Planar (singlet) (ii) Linear (triplet)
Magnetism	Paramagnetic	Diamagnetic	Diamagnetic	(i) Diamagnetic (ii) Paramagnetic
