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 :
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✓ Correct
- (D)Statement I is true but Statement II is false
Answer: (C)
Solution
Statement I: Down a group among transition elements, higher oxidation states become more stable (e.g. for Mo/W is more accessible than for Cr), unlike the p-block trend where higher oxidation states become less stable down the group (inert pair effect). This is correctly stated — Statement I is true.
Statement II: V V, so Cu cannot reduce H to H from a weak (or dilute) acid — Statement II is true.
Both statements are true.
Statement II: V V, so Cu cannot reduce H to H from a weak (or dilute) acid — Statement II is true.
Both statements are true.
