Reverse Hyperconjugation : The method of hyperconjugation is as well observed in the system given below,
In such type of system the effect operates in the opposite direction. Therefore the hyperconjugation in such system is termed as reverse hyperconjugation.
The deactivating effect and meta directing affect of CX3 group in electrophilic aromatic substitution reaction can be described by this effect.
