In Tollen's reagent, the oxidation number, coordination number and effective atomic number of central metal ion are respectively [atomic number of Ag - 47] :

A

`+1,2,50`

B

`+1,2,51`

C

`2,+1,50`

D

`+1,1,50`

Text Solution

Verified by Experts

The correct Answer is:
A
Tollen.s reagent is `[Ag(NH_(3))_(2)]^(4)`
Oxidation no of silver `=x+2(0)=+1orx=+1`. As there are two s bonds between silver and ligands its coordination number is 2. EAN = `(47-1)+2xx2=50`.
