Compare thermal stability of and
Compare thermal stability of \( Z n O \) \( C d O \) and \( H g O \)
- A. \( Z n O>C d O>H g O \)
- B. \( C d O>Z n O>H g O \)
- C. \( Z n O>H g O>C d O \)
- D. \( H g O>Z n O>C d O \)
Step-by-step solution
Thermal stability of metal oxides in Group 12 decreases down the group due to increasing atomic size and decreasing bond strength. ZnO is the most stable, followed by CdO, while HgO decomposes at the lowest temperature.
