Q7. A compound with empirical formula Co(NH₂),BrSO exist in two forms red and violet. Solution of red colour gives a precipitate of AgBr on addition of AgNO3. The violet form gives no precipitate on addition of AgNO, but gives a white precipitate on addition of BaCl, solution. The structure of red and violet colour complex is (a) [Co(NH₂),SO], [Co(NH3),Br]²+ respectively (b) [Co(NH₂),SO 1¹²¹, [Co(NH₂),Br]²+ respectively (c) [Co(NH₂),SO]²+, [Co(NH₂),Br]³+ respectively (d) [Co(NH3)5Br], [Co(NH3)5SO4]* respectively Q7.
