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
