The oxidation state of Cr in [Cr(NH(3))(...

The oxidation state of `Cr` in `[Cr(NH_(3))_(4)Cl_(2)]^(+)` is:

A

`+3`

B

`+2`

C

`+1`

D

0

Text Solution

Verified by Experts

The correct Answer is:
A
`[Cr(NH_(3))_(4)Cl_(2)]^(+)`
Let O.S. of Cr = x
`x + 4 xx 0 + 2 xx (-1) = +1`
`x -2 = 1`
x = `+3`
