How will you convert nitrobenzene into (i)1,3,5-trinitrobenzene (ii)

1.	How will you convert nitrobenzene into (i)1,3,5-trinitrobenzene (ii) o and p-nitrophenol (iii) m-nitro aniline (iv). Azoxybezene v. Hydrozabenzene vi. N-phenylhydroxylamine (vii). Aniline.
Answer» Solution :(i)CONVERSION of NITROBENZENE into 1,3,5-trinitrobenzene: (ii) Conversion of nitrobenzene into o and p-nitrophenol: a. Method I: Nitrobenzene heated with solid KOH AR 340 K gives a low yield of a mixture of O and P nitrophenols. (iii) Conversiion of nitrobenzene into m-nitro aniline: (iv). Conversion of nitrobenzene into azoxybenzene: `underset (("nitrobenzene"))(2C_(6)H_(5)NO_(2))underset(("or")"Glucose"//NaOH Delta)overset(Na_(3)AsO_(3)//NaOHDelta)(to)C_(6)H_(5)-underset(("azoxybenzene")) underset(O)underset(darr)(N)=N-C_(6)H_(5)` v. Conversion of nitrobenzene into hydrazobenzen: `underset(("nitrobenzene"))(2C_(6)H_(5)NO_(2))overset(Zn//NaOH)(to)underset(("Hydrazobenzene"))underset(C_(6)H_(5)-NH-NH-C_(6)H_(5))underset(darr2(H))([C_(6)H_(5)-N=N-C_(0)H_(5)])` (vi). Conversion of nitrobenzene into N- phenylhydroxylamine: `underset(("nitrobenzene"))(C_(6)H_(5)NO_(2))underset(H_(2)O,Delta)overset(Zn//NH_(4)Cl)(to)underset(("N-Phenylhydrozylamine"))(C_(6)H_(5)-NHOH+ZnO)` (VII). Conversion of nitrobenze into aniline:
