Write the IUPAC name for the following complexes [ Ag (CN)2]- |
|
Answer» Actually, the question is wrong, as silver can only carry a unipositive charge. This is so because Ag(Z=47) has electronic configuration as 1s2,2s2,2p6,3s2,3p6,4s2,3d10,4p6,5s1,4d10. It has only one unpaired ELECTRON in 4s ORBITAL, which it donates & becomes Ag+ ion. Since cyanide ion has a uninegative charge, the negative charge of one CN− ion would be balanced by the Ag+ ion & the WHOLE COMPLEX will carry a uninegative charge. THUS the compound would be [Ag(CN)2]−. Now its IUPAC name is Dicyanidoargentate(I) ion If there is no complex formation, then the compound would be AgCN & then its name would be Silver cyanide |
