A) 6, 5, 4
B) 3, 2, 1
C) 0, 1, 2
D) 3, 3, 3
Correct Answer: B
Solution :
The complexes can be written as follows \[\underset{\text{(A)}}{\mathop{[Co{{(N{{H}_{3}})}_{6}}]C{{l}_{3}}}}\,\,\underset{\text{(B)}}{\mathop{[Co{{(N{{H}_{3}})}_{5}}Cl]C{{l}_{2}}}}\,\]\[\underset{\text{(C)}}{\mathop{[Co{{(N{{H}_{3}})}_{4}}C{{l}_{4}}]Cl}}\,\] Hence, number of primary valencies are 3, 2 and 1 respectively.You need to login to perform this action.
