Question

Copper exhibits only $+2$ oxidation state in its stable compounds. Why?

• A. Copper is transition metal in $+2$ state
• B. $+2$ state compound of copper are formed by exothermic reactions
• C. Electronic configuration of copper in $+2$ state in $\left[Ar\right]3d^{9}4s^0$
• D. Copper gives coloured compounds in $+2$ state

Answer 1

The correct option is B $+2$ state compound of copper are formed by exothermic reactions

Copper exhibits only $+2$ oxidation state in its compound because $+2$ state of copper are formed by exothermic reaction.
