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:

Canvas Classes · Accepted Answer

Statement I: Higher oxidation states more stable down the group in transition metals

This is TRUE ✓

In d-block, going down a group (e.g., Fe → Ru → Os), higher oxidation states become more stable:
- Fe: +2, +3 common; +6 (FeO₄²⁻) rare
- Ru: +4, +6, +8 common
- Os: +8 (OsO₄) very stable

This is opposite to p-block where lower oxidation states are more stable down the group (inert pair effect).

Statement II: Cu cannot liberate H₂ from weak acids

This is TRUE ✓

Cu has  V (positive), so it lie
