Question 7 Which of the following statements are true about the deactivating nitroso substituent in electrophilic aromatic substitution reactions? NFO The nitroso group is predicted to be an ortho/para-directing group. Resonance withdrawing effects can explain why the nitroso group is deactivating. The nitroso group is predicted to be an meta-directing group. Inductive withdrawing effects can explain why the nitroso group is deactivating.

Question 3. [time 4 + 8 = 12 minutes) (a) i. Both the regioselectivity and the rate of an electrophilic aromatic substitution are affected by the substituents already attached to the benzene ring. Some groups promote substitution at the ortho or para positions, while other groups increase substitution at the meta position. Explain the terms "resonance effect" and "inductive effect" of substituents (use words and schemes). ii. Explain, using words and schemes, how in electrophilic aromatic substitutions existing substituents direct...
