Plz solve rtisjwj jekwgdsiow

Dear Student, Oxidizing agents are those which themselves get reduced. It means on oxidation by V2O5, the electrons from aromatic ring will move to V2O5. Now, the OH bearing ring has higher electron density due to +R effect of -OH group, and hence will donate electrons easily. So, oxidation will occur at this ring. Correct answer is (1). Regards
