One mole of MnO_(4)^(2-) disproportionates to yield :

Se_(2)Cl_(2)overset(Delta)toSeCl_(4)+Se

Se_(2)Cl_(2)overset(Delta)toSeCl_(4)+Se

Write the disproportionate reaction of MnO_(4)^(2-) ?

On nuclear chlorination, C_(8), H_(10) (A) gives a product (B) which may be oxidised to C_(8) H_(5)O_(4)Cl(C). (A) may alos be chlorinated to give C_(8) H_(8) Cl_(2)(D), C_(8) H_(6)Cl_(4)(E) , and C_(8) H_(4) Cl_(6)(F). (D), (E) and (F) on hydrolysis give halogen-free compounds (G), (H) , and (I) , respectively. With CrCO_(2)Cl_(2), (A) gives C_(8) H_(6)O_(4) which is identiacla with (I) . Identify wtih (I) . Identify the varioius compounds (A) to (J) .

Colouration of Br_(2)//C Cl_(4) will be discharged by
