Werner proposed coordination theory to explain the properties and stuructures of various metal ammines of cobalt, chromium, platinum, etc. It was first successful attempt which satisfactorily described the formation of coordination compounds from stable molecules. Which of the following has higher molar conductance ?

Answer»

`[Co(NH_(3))_(5)Br]SO_(4)`
`[Co(NH_(3))_(5)SO_(4)]Br`
Both (a) and (B)
None of these

Solution :`[Co(NH_(3))_(5)Br]^(2+)"" SO_(4)^(2-)` has GREATER MOLAR conductnace than `[Co(NH_(3))_(5)SO_(4)]^(+) Br^(-)`
