Which of the following statements regarding the Effective Atomic Number (EAN) calculations for the s — Coordination Compounds Chemistry Question

💡 Solution & Explanation

Using the formula $EAN = Z - x + 2(C.N.)$: (A) Pd(46) in $[Pd(NH_3)_6]^{4+}$: $EAN = 46 - 4 + 12 = 54$. (True) (B) Ag(47) in $[Ag(CN)_2]^-$: $EAN = 47 - 1 + 4 = 50$. (True) (C) Ni(28) in $[Ni(CN)_4]^{2-}$: $EAN = 28 - 2 + 8 = 34$. (False, it is not 36). (D) Pt(78) in $[PtCl_6]^{2-}$: $EAN = 78 - 4 + 12 = 86$. (True)
