JEE Mains · Chemistry · STD 12 - 4. d and f- block elements
Given 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 :
- A Both Statement \(I\) and Statement \(II\) are false
- B Statement \(I\) is false but Statement \(II\) is true
- C Both Statement \(I\) and Statement \(II\) are true
- D Statement \(I\) is true but Statement \(II\) is false
Answer & Solution
Correct Answer
(C) Both Statement \(I\) and Statement \(II\) are true
Step-by-step Solution
Detailed explanation
On moving down the group in transition elements, stability of higher oxidation state increases, due to increase in effective nuclear charge. \( \Rightarrow \mathrm{E}_{\mathrm{Cu}^{+2} / \mathrm{Cu}}^{\circ}=0.34 \mathrm{~V} \)…
