A coordination compound has the formula `CoCl_3 .4NH_3`. It precipitates silver ions as AgCl and its molar conductance corresponds to a total of two ions. Replace ammonia molecules by two molecules of ethylenediamine and discuss isomerism in the resulting complex ion.

A coordination compound has the formula CoCl_3 .4NH_3 . It precipitates silver ions as AgCl and its molar conductance corresponds to a total of two ions. Deduce its structural formula and name the complex.

A coordination compound CrCl_3 .4H_2O precipitates silver chloride with AgNO_3 . The molar conductivity of the solution corresponds to a total number of two ions. Write structural formula of the compound and name it.

On reaction with silver nitrate solution, the complex CoCl_3 .4NH_3 gives precipitates corresponding to one/two chloride ions.

A coordination complex compound of cobalt has molecular formula containing five ammonia molecules, one nitro group and two chlorine atoms for one cobalt atom. One mole of this compound produces three mole ions in an aqueous solution. On reacting this solution with excess of silver nitrate solution, two moles of AgCl get precipitated. The formula of this compound would be

The complex CoBr_3 .4NH_3 .2H_2O has molar conductivity corresponding to 1:3 electrolyte, Write the molecular formula and its IUPAC name.

Assertion : ([Fe(CN)_6]^(3-) ion shows magnetic moment corresponding to two unpaired electrons. Reason : Because it has d^2sp^3 type hybridisation

A Compound with the empirical formula Co(NH_3)_5 BrSO_4 exists in two forms : red and violet. Solution of red gives a precipitate of AgBr on addition of AgNO_3 . The violet form Sives no precipitate on the addition at AgNO_3 but gives a white precipitate on addition of BaCl_2 solution. From these observations draw the structure of each compound and explain the observations.

Ammonia forms the complex ion [Cu(NH_3)_4]^(2+) with copper ions in alkaline solutions but not in acidic solution. The reason for this is
