STANDARD Chemistry Conductivity MCQ Question
Type: MCQ-conceptual-Medium-Class 12
Arrange the following complexes in increasing order of conductivity of their solutions. (i) [Co(NH₃)₃Cl₃] (ii) [Co(NH₃)₄Cl₂]Cl (iii) [Co(NH₃)₆]Cl₃ (iv) [Co(NH₃)₅Cl]Cl₂
A
(i) < (ii) < (iv) < (iii)
B
(ii) < (i) < (iii) < (iv)
C
(i) < (iii) < (ii) < (iv)
D
(iv) < (i) < (ii) < (iii)
Correct Answer
Option A
Detailed Explanation
Higher the number of ions in the solution, higher is the conductivity. No. of ions: [Co(NH₃)₃Cl₃] = 0; [Co(NH₃)₄Cl₂]Cl = 2; [Co(NH₃)₅Cl]Cl₂ = 3; [Co(NH₃)₆]Cl₃ = 4
