Concept explainers
(a)
Interpretation:
All resonance structures for the carbocation of given compound formed by ortho attack of the electrophile
Concept introduction:
Resonance structure is a blend of two or more Lewis structures. Resonance structures are represented by a double headed arrow between the structures.
(b)
Interpretation:
All resonance structures for the carbocation of given compound formed by ortho attack of the electrophile
Concept introduction:
Resonance structure is a blend of two or more Lewis structures. Resonance structures are represented by a double headed arrow between the structures.
(c)
Interpretation:
All resonance structures for the carbocation of given compound formed by ortho attack of the electrophile
Concept introduction:
Most of the organic structures cannot be represented using single Lewis structure. Therefore, there exists more than one Lewis structure for representing a molecule or ion. These structures are known as resonance structures.

- Draw the least stable resonance form for the intermediate in the following electrophilic substitution reaction. CEN Br₂/FeBra • You do not have to consider stereochemistry. Include all valence lone pairs in your answer. In cases where there is more than one answer, just draw one. Br CEN Iarrow_forwardAll electrophilic aromatic substitution reactions occur via a two-step mechanism: addition of the electrophile to form a resonance-stabilized carbocation, followed by deprotonation by a base. In the step shown below, loss of a proton to form the substitution product was drawn using the resonance structure with the + 1 formal charge at the ortho position to the carbon bonded to the electrophile. Redraw the step shown with the other two resonance structures and use curved arrows to show how these other two resonance structures can be converted to the substitution product by removal of a proton with the base shown.
