Objectives - Section 1 • Identify a substituent as an ortho para director or a meta director, Draw the resonance structure that explains the relative directing ability of a specific substituent. Classify a substituent as an activating or a deactivating group. Explain why the halogens are ortho/para directors but are deactivators. • 1.

Activating groups "speed up" electrophilic substitution of
aromatics and deactivating groups "slow down" electrophilic
substitution.
1. Ignoring halogens, what is different between the composition
of the ortho-para directors and the meta directors?
2. What causes the deactivating groups to "slow down" the
substitution? What may be used to speed up these reactions?
3. How does carbocation stabilization affect the orientation of
the products in each orientation?

Which of the following statements are true about the deactivating nitroso substituent in electrophilic aroman -N=0 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.
