Question

Thank you so much 37. Choose the correct statement. a) Nitrile groups are strongly activating in electrophilic aromatic substitutions since they donate electron density to the ring. b) Alkyl groups are activating in electrophilic aromatic substitutions since they donate electron density to the ring. c) Alkyl groups are deactivating in electrophilic aromatic substitutions since they have a lower energy of activation than benzene in the addition of the electrophile to the aromatic ring.- d) The trifluoromethyl group is deactivating in electrophilic aromatic substitutions since it withdraws electron density via resonance. e) The trifluoromethyl group is an ortho,para director in electrophilic aromatic substitutions since it donates electron density via resonance. 38.
