Question

Give below are two statements: Statement I : The higher oxidation states are more stable down the group among transition elements unlike p-block elements. Statement II : Copper can not liberate hydrogen from weak acids. In the light of the above statements, choose the correct answer from the options given below :

TestHub · Accepted Answer

On moving down the group in transition elements, stability of higher oxidation state increases, due to increase in effective nuclear charge. ​ ⇒ E Cu + 2 / Cu ∘ ​ = 0.34 V ⇒ E H + / H 2 ​ ∘ ​ = 0 SRP : Cu 2 + > H + ​ Cu can't liberate hydrogen gas from weak acid.
