Question

Arrange the following complexes in the increasing order of conductivity of their solution
`[Co(NH_(3))_(3)Cl_(3)], [Co(NH_(3))_(4)Cl_(2)]Cl, [Co(NH_(3))_(6)]Cl_(3), [Cr(NH_(3))_(5)Cl] Cl_(2)`
A. `(i) lt (ii) lt (iv) lt (iii)`
B. `(ii) lt (i) lt (iii) lt (iv)`
C. `(i) lt (iii) lt (ii) lt (iv)`
D. `(iv) lt (i) lt (ii) lt (iii)`

Answer 1

Correct Answer - A
Higher the number of ions in the solution , higher is the conductivity .
No. of ions : `[Co(NH_(3))_(3) Cl_(3)] = 0 , [Co(NH_(3))_(4)Cl_(2)]Cl = 2`
`[Co(NH_(3))_(5) Cl]Cl_(2) = 3 , [Co(NH_(3))_(6)]Cl_(3) = 4`
