Aromatic Substution Flashcards
Kya benzene ring pr aromatic substitution Kar sate hai
No
Because substituted aromatic system caheiye Hota Hai
In addition then elimination process rate of rxn directly proportional to the
Concentration of substrate aur nucleophile
Nature of EWG
NUCLEOPHILICITY OF NUCLEOPHILE
Intra or intermolecular me koine si reactions favourable hoti hai
Intra
In smle rearrangement the fist reaction occurs
Acid base rxn
This reaction always taking place first
When in benzene ring EWG in ortho or para positions not present then which mechanism will be followed
Elimination then addition

2 products
The major product formed in benzyne rxn are
EWG ke pass negative group hons cahiye
In which mechanism only inductive effect of group is considered
Benzyne formation
