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 \[\underset{(A)}{\mathop{\left[ Co{{\left( N{{H}_{3}} \right)}_{6}} \right]}}\,C{{l}_{3}}\,\underset{(B)}{\mathop{\left[ Co{{\left( N{{H}_{3}} \right)}_{5}}\,Cl \right]}}\,C{{l}_{2}}\] \[\underset{(C)}{\mathop{\left[ Co{{\left( N{{H}_{3}} \right)}_{4}}C{{l}_{4}} \right]}}\,Cl\] Hence, number of primary valencies are 3, 2 and 1 respectively.You need to login to perform this action.
