Interpretation:
The carbocation intermediate has to be drawn and resonance structure has to be drawn for the carbocation.
Concept Introduction:
Unimolecular nucleophilic substitution reaction
- Loss of leaving group, where the loss of leaving group from the substrate gives a carbocation intermediate.
- Nucleophilic attack: A nucleophile attacks the carbocation intermediate to afford the product.
Leaving group: It is a fragment that leaves substrate with a pair of electrons via heterolytic bond cleavage.
Nucleophile: Donates pair of electrons to positively charged substrate resulting in the formation of
Resonance is an electron displacement effect for stabilizing a molecule through delocalization of bonding electrons in the pi orbital.
Delocalized electrons stabilize a compound. The extra stability gains from having delocalized electrons are called resonance stabilization or resonance energy.
