Q12 of 36 Page 1

Write structures of compounds A and B in each of the following reactions:


(i)The steps involve oxidation of ethyl benzene in presence of oxidising agents


So, Product A is formed by the oxidation of Ethyl Benzene and after hydrolysis of Product A, Benzoic Acid is formed, which is Product B.


(ii) The steps involve oxidation of ethyl benzene in presence of oxidising agents and



Product A is formed by the ozonolysis of Phenol and Product B is the process of addition of NNHCONH2 and removal of OOxygen atom.
