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.
