Why is Cu+ not stable in aqueous solution?
Why is Cu+ not stable in aqueous solution?
- It has a high negative ∆hydHθ value (correct)
- Due to the presence of unpaired electrons
- Due to high reduction potential
- It can easily compensate for 2nd ionization potential of Cu
Why do oxygen and fluoride oxidize metals to their highest oxidation state in oxides or fluorides?
Why do oxygen and fluoride oxidize metals to their highest oxidation state in oxides or fluorides?
- Their small size and high electronegativity make them efficient oxidizing agents (correct)
- Because they have high positive reduction potential
- They possess unpaired electrons in their valence shell
- Due to their large size and low electronegativity
