Question

-
A complex has a composition corresponding
to the formula CoBr2Cl.4NH3. What is the
structural formula if conductance
measurements show two ions per formula
unit ? Silver nitrate solution given an
immediate precipitate of AgCl but no AgBr:-
(1) [CoBrCl(NH3)4]Br
(2) [CoCl(NH3)4]Br2
(3) [CoBr2CI(NH3)4]
(4) [CoBr2(NH3)4]Cl
Plz anyone rply it with explanation...... ​

Answer 1

fourth option is a correct.

due to presence of Cl^-1ion it can give agcl as a precipitate with silver nitrate solution.
