[JMatthes]

Based on the electronic structure, what kind of substituent effect would you expect from the nitroso group?
 
  1. o,p-directing, deactivating
  2. o,p-directing activating
  3. m-directing, activating
  4. m-directing, deactivating

Question 2

Which of the following represent the intermediate formed in the reaction between p-chloronitrobenzene and hydroxide ion?
 

Question 3

Fluorine is less deactivating than chlorine in the aromatic electrophilic substitution reactions. What is the main reason for this reactivity trend?
  1.Fluorine forms stronger  bonds than chlorine, providing more resonance stabilization.
  2.Chlorine is more electronegative than fluorine.
  3.Because of it size chlorine has stronger inductive influence than fluorine.
  4.Fluorine is smaller, making the entry of electrophiles easier.
  5.Chlorine forms complexes with electrophiles, diminishing their reactivity.
