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.

- 7. The reaction of methoxide anion with bromoethane to yield the ether ethyl methyl ether and the bromide anon (Br-) is an excellent example of a general reaction type called Sy2 (substitution nucleophilic bimolecular): CH,0+ CH,СH-Br a CH3-0-CH,СH; + Br- a. Change in enthalpy is -103 kJ/mol; the change in entropy is + 0.025 kJ/mol-K. Calculate DG at 300K. b. Is the reaction endergonic or exergonic? c. Is the reaction endothermic or exothermic? d.

- Draw a structural formula for the major product of the reaction shown.arrow_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.
