Unformatted text preview: neutralization equivalent of 131 +/- 2 . When sample (Z) was treated with aqueous NaOH a liqiud separated ; it contained nitrogen but no chlorine . Further treatment of the liquid with nitrous acid followed by hypophosphorous acid gave benzene . Write a structure for (Z), and write equations for all the reactions . 7. Compound (A) C 10 H5 is easily oxidized in the presence of ozone and then followed by water to compound (B) CgHgC^ . When compound (A) is treated with hydrogen in the presence of Ni (heat + mild pressurre ) compound (c) C-|QH-|4 results. If com-pound (c) is treated with acidic permanganate solution , compound (B) results . Compound (B) has a neutralization equivalent of 83 . When (B) is treated with Ferric bromide and Br 2 only one monobrominated derivative is possible . Write structures for A,B. andC....
