Which of the following complexes has lowest molar conductance ?

A

`[Co(NH_(3))_(6)][Cr(NO_(2))_(6)]`

B

`[Cr(NH_(3))_(5)(NO)_(2)][Co(NH_(3))(NO_(2))_(5)]`

C

`[Cr(NH_(3))_(4)(NO_(2))_(2)][Co(NH_(3))_(2)(NO_(2))_(4)]`

D

`[Co(NH_(3))_(5)(NO_(2))][Cr(NH_(3))(NO_(2))_(5)]`

Text Solution

Verified by Experts

The correct Answer is:
C
(c ) `[Cr(NH_(3))_(4)(NO_(2))_(2)]^(+)`
`[Co(NH_(3))_(2)(NO_(2))_(4)]^(-)`
has the lowest ionic charge.
