I know correct answer is c. However what type of
directors are A and B (meta directors ) ??? Please explain
conceptually . Thank you!
Homework Answers
Yes. A & B are strongly deactivating groups. Hence meta directing groups.
Some meta directing groups. are: -NO2, -NR3+,
-NH3+, -SO2-OH, -C
N,
-CF3, C=O-Cl
Explanation:
Electron Donating Groups / activating groups direct ortho / para
Electron Withdrawing Groups / deactivating groups direct meta
except halogens (-X) which are deactivating BUT direct ortho / para.

MULTIPLE ANSWER CHOICES ARE POSSIBLE (more than one correct)
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.

Hi please can you help me understand how to answer this question "If p-nitrophenol is treated with chlorine in the presence of ALCL3 the only trisubstituted product observed is: 2 chloro -4nitrophenol I am confused because p nitrophenol has both an OH group which is an ortho and para activating group and a NO2 which is a deactivating meta group. Which one would take priority when undergoing the reaction?
i know that C is a meta director, but are any of these ortho
or para, or any other kind of directors? thanks!
