Magnetic moment, ionic conductance and colligative properties are useful in deciding structure. constitution of a given unknown complex compound.
If molar conductivity of complex is almost equal to that of $$NaCl$$ and it does not exhibits stereoisomerism then the complex will be
A
$$[Co(CO_{3})(en)_{2}]Br$$
B
$$[Co(CO_{3})(H_{2}O)_{2}(NH_{3})_{2}]Br$$
C
$$[Co(CN)(NH_{3})_{5}]Br_{2}$$
D
$$[Co(CO_{3})(NH_{3})_{4}]Br$$
Correct option is D. $$[Co(CO_{3})(NH_{3})_{4}]Br$$
The complex $$[Co(CO_{3})(NH_{3})_{4}]Br$$ has a molar conductivity similar to as that of NaCl and it also does not show stereo Isomerism.
Hence, Option "D" is the correct answer.
