1.	The electronic configuration of Cu(II) is 3d9 whereas that of Cu(I) is 3d10. Which of the following is correct? [NCERT Exemplar] (a) Cu(II) is more stable (b) Cu(II) is less stable (c) Cu(I) and Cu(II) are equally stable (d) Stability of Cu(I) and Cu(II) depends on nature of copper salts
Answer» is more stable,i.e, OPTION 1 is correct..Even if the CONFIGURATION of Cu+1 is more stable but CU2+ will be more stable DUE to very HIGH HYDRATION ENERGY..Hope it helps ya:)
