Text Solution

Verified by Experts

The correct Answer is:
(a)
`[CoCl_3xx Nh_3 +AgNO_3 to Agcl ]`
since 1 mole of Agcl is formed only one Clis present outside the coordination sphere i.e, `[CoCl_2xx NH_3] Cl`
coordiantion number Co is 6. As Co is already bonded to two Cl atoms, it can bond to another four `NH_3` molecules
Therefore X= 4.
