CoSO_(4)Cl.5 NH_(3) exists in two isomeric forms 'A' and 'B'. Isomer 'A' reacts with AgNO_(3) to give white precipitate, but does not react with BaCl_(2) . Isomer 'B' gives white precipitate with BaCl_(2) but does not react with AgNO_(3) . Answer the following questions. (a) Identify 'A' and 'B' and write their structural formulae. (b) Name the type of isomerism involved. (c) Give the IUPAC name of 'A' and 'B'.
