Question

Write reaction of following transformation and give the name of organic compounds according to IUPAC: ethyne → benzene → nitrobenzene → ?-dinitrobenzene​

Answer 1

Methyl benzoate is the ester of benzene. It can easily be prepared after preparing benzoic acid. So, we can form benzoic acid by Friedel Craft alkylation and then form an ester, we can just oxidize the formed acid to get methyl benzoate. The process is called esterification.
