Which of the following sets of substituents are all ortho/para directing in electrophilic aromatic substitution reactions? O CN, NO2, COCH3 O CI, OH, CH3 OBr, OH, COCH3 OCI, CH3. CN
QUESTION 2 Which statement is true with respect to the directing effects of bromine and methoxy groups in electrophilic aromatic substitution reactions? Both Brand OMe are meta directors Both Br and OMe are ortho/para directors Br is a meta director and OMe is an ortho/para director Br is an ortho/para director and OMe is a meta director
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? Activating groups Deactivating groups ortho-, para- directors -hydroxyl (OH) -alkoxy (OR) -amino (NH2, NR)...
