Explain why this ring is not participating as effectively in resonance. အ a 9 or O Ring D is not participating in resonance because the positive charge would be unstable there. There is additional resonance stabilization because of ester group in ring D. O Ring D is too far away from the positive charge to be involved in resonance. O Because of crowding, ring D is out of planarity of other three rings and the p orbitals don't overlap.

A benzene ring alters the reactivity of a neighboring group in the so-called "benzylic" position, similarly to how a double bond alters the reactivity of groups in the "allylic" position.

Draw all the resonance structures A through D and explain why one resonance structure is more favourable than the other three in directing the electrophile (E*) ortho to the OH functional group.2. Draw all resonance structures for nitrobenzene and phenol below. Substituents on an aromatic ring can affect the rate of electrophilic aromatic substitution as well as the stereochemistry (ortho, meta, para) of the product. Briefly explain how this works. See Text: 15.10 (10th ed.) NO2 OHWhich of the following statements best describes the molecule below? NH₂ The ring is deactivated in electrophilc aromatic substitution because N is electronegative and withdraws electron density from the ring. The ring is activated in electrophilc aromatic substitution because the lone pair on N can donate electron density to the ring. The ring is activated in electrophilc aromatic substitution because N is electronegative and withdraws electron density from the ring. The ring is deactivated in electrophilc aromatic substitution because the lone pair on N can donate electron density to the ring.
