In coordination chemistry there are a variety of methods applied to find out the structure of complexes. One method involves treating the complex with known reagents and from the nature of raction, the formula of the complex can be predicted. An isomer of the complex Co(en)_(2)(H_(2)O)Cl_(2)Br, on reaction with concentrated H_(2)SO_(4) (dehydrating agent), suffers loss in weight and on reaction with AgNO_(3) solution it gives a white precipitate which is soluble in NH_(3)(aq).

1.	In coordination chemistry there are a variety of methods applied to find out the structure of complexes. One method involves treating the complex with known reagents and from the nature of raction, the formula of the complex can be predicted. An isomer of the complex Co(en)_(2)(H_(2)O)Cl_(2)Br, on reaction with concentrated H_(2)SO_(4) (dehydrating agent), suffers loss in weight and on reaction with AgNO_(3) solution it gives a white precipitate which is soluble in NH_(3)(aq). The number of geometrical isomers of the formula fo the above original complex are (including the complex) :
Answer» 2 3 4 1 Solution :`[M(AA)_(2))AB] implies"cis form and trans form"`.
