D and F Block Elements question

2024 · 9 Apr · Shift 1 · Q9

JEE MainChemistryD and F Block ElementsMCQ+4 / −1
The electronic configuration of Cu(II)\mathrm{Cu}(\mathrm{II})Cu(II) is 3 d93 \mathrm{~d}^93 d9 whereas that of Cu(I)\mathrm{Cu}(\mathrm{I})Cu(I) is 3 d103 \mathrm{~d}^{10}3 d10. Which of the following is correct?
  1. A
    Cu(II)\mathrm{Cu}(\mathrm{II})Cu(II) is more stable
  2. B
    Cu\mathrm{Cu}Cu (II) is less stable
  3. C
    Cu(I)\mathrm{Cu}(\mathrm{I})Cu(I) and Cu(II)\mathrm{Cu}(\mathrm{II})Cu(II) are equally stable
  4. D
    Stability of Cu(I)\mathrm{Cu}(\mathrm{I})Cu(I) and Cu(II)\mathrm{Cu}(\mathrm{II})Cu(II) depends on nature of copper salts
