(a)
Interpretation:
The helpless of blocking group to achieving the given reaction should be explained.
Concept Introduction:
Electrophonic aromatic substitution:
The atom or group which is directly attached to an
Blocking group:
The aromatic substitution reaction take place in substituted aromatic system the blocking group is introduce first to protect the reacting position (ortho, meta, para) of the electrophonic or nucleophile then electrophonic or nucleophile reacting then remove the blocking group after completion of the reaction to give required substituted product.
(b)
Interpretation:
The helpless of blocking group to achieving the given reaction should be explained.
Concept Introduction:
Electrophonic aromatic substitution:
The atom or group which is directly attached to an aromatic compound is replaced by an electrophile is called Electrophonic aromatic substitution reaction.
Blocking group:
The aromatic substitution reaction take place in substituted aromatic system the blocking group is introduce first to protect the reacting position (ortho, meta, para) of the electrophonic or nucleophile then electrophonic or nucleophile reacting then remove the blocking group after completion of the reaction to give required substituted product.
