Stability constant is more for the complex:A. (a) `[Ag(NH_3)_2]^(+)`B. (b) `[Cu(NH_3)_4]^(2+)`C. (c) `[Ag(CN)_2]^(-1)`D. (d) `[Co(NH_3)_6]^(3+)` |

Answer» Correct Answer - D Complex will be more stable if higher value of charge density is present. `"Charge density" = "Charge"/ "Radius"` For stability: (i) More basic ligand, then complex will be more stable. (ii) Higher the oxidation state of central atom and higher is its coordination number. (iii) Higher the stability constant (K) `{:(,,[Co(NH_3)_6]^(3+),,[Cu(NH_3)_4]^(2+)),(Stability,,darr,,darr),(const ant(K),,5xx10^(33),,4xx10^(11)),(,,[Ag(NH_3)_2]^(+),,[Ag(CN)_2]^(-1)),(Stabil ty,,darr,,darr),(const ant(K),,1.6xx10^7,,1xx10^(22)):}` |
