What is the oxidation number of gold in the complex `[AuCl_(4)]^(1-)` ?

A

`+4`

B

`+3`

C

`+2`

D

`+1`

Text Solution

Verified by Experts

The correct Answer is:
B
Let x be the oxidation number of gold (Au) in the complex `[AuCl_(4)]^(-1)`
`:." "x+4(-1)=-1`
`rArr" "x=-1+4`
`rArr" "x=+3`
Hence, the oxidation number of gold is `+3`
