Nitrobenzene is formed as the major product along with a minor product in the reactionof benzene witha hot mixture of nitric acid and sulphuric acid. The minor product consists of carbon: 42.86%, Hydrogen:2.4%, nitrogen:16.67% and oxygen:38.07%
i) calculate the emprical formula of the minor product
ii) when 5.5 g of the minor prouct is didsolved in 45 g of benzene, the boiling point of the solution is 1.84 degree C higher than that of pure benzene. Calculate the molar mass of the minor product and determine itsmolecular and structural formula.
Molal boiling point elevation constant of benzene is 2.53 K kg/ mol

21Assuming no dimerization & no diss. we get x =2;
So MF = C6H4N2O4
matlab : structural formulae :
