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.
