Given the molecular formula of the hexacoordinated complexes (A) `[CoCl_(3).6NH_3]` (B) `[CoCl_(3).5NH_3]` (C) `CoCl_(3).4NH_3`. If the number of coordinated `NH_3` molecules in A, B and C respectively are 6, 5 and 4, the primary valency in (A), (B) and (C) are:

A

6, 5, 4

B

3, 2, 1

C

0, 1, 2

D

3, 3, 3

Text Solution

Verified by Experts

The correct Answer is:
B
Hence, number of primary valencies are 3, 2 and 1 respectively.
