QUESTION:
Problem 4P
Use resonance forms to show that the dipolar sigma complex shown in the sulfonation of benzene has its positive charge delocalized over three carbon atoms and its negative charge delocalized over three oxygen atoms.
ANSWER:
Solution:
Here we have to show the resonance structure of delocalization of+ve and -ve charge on sulfonation of benzene
Step 1
Resonance structure of delocalization of +ve charge on benzenesulfonic acid (benzene ring):-
Her the +ve charge is delocalized on the benzene ring . In all the resonance structures the +ve charge is delocalized on the 2o carbon atom.
