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.

EASY QUESTION! Williamson ether synthesis lab question. meta-cresol+chloroacetic acid with KOH as a base. I found my unknown compound which was meta cresol by comparing the MP, but I cannot find the correct MP for meta cresol. I was told the MP for meta cresol is around 100 degrees C, and I was trying to look up a more accurate value then just "around 100 C" but every source I'm finding says the MP is 10-11 C. If the MP...

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.
