The salts of Cu in +1 oxidation state are unstable because

Options

A. `Cu^(+)` has `3d^10` configuration
B. `Cu^+` disproportionates easily to Cu(0) and `Cu^(2+)`
C. `Cu^+` disproportionates easily to `Cu(2+)` and `Cu^(2+)`
D. `Cu^+` is easily reduced to `Cu^(2+)`

Answer

B

Explanation

`Cu^+` ions undergo disproportionation .
`2Cu^(+) to Cu^(2+) + Cu`
