The selective reagents used to accomplish the given statement of starting molecule into target products (major product) transformation should be draw and identified. Concept introduction: Friedel-Crafts alkylation : This reaction electrophilic aromatic substitutions allows the synthesis of monoacylated ( R − C O − C H 3 ) products from the reaction between arenes and acyl chlorides (or) anhydrides. The obtained products are deactivated and go not undergo a second substitution place.

Nitration Reaction : This type of aromatic electrophilic substitution reaction the nitration syntheses apply called "mixed acid", a mixture of concentrated H N O 3 and H 2 S O 4 . This mixture produces the nitronium ion ( N O 2 + ), which is the active species in aromatic nitration. This active ingredient, which can be isolated in the case of nitronium tetrafluoroborate, also effects nitration without the need for the mixed acid. In the case of nitration of benzene, the reaction is conducted at a warm temperature the process is one example of electrophilic aromatic substitution, which involves the attack by the electron-rich benzene ring.
