[:S=N-c: 1 In the above polyatomic anion, what is the formal charge on: S? Answer: [:S=N-C: 1! In the above polyatomic anion, what is the formal charge on: N? Answer: [:S=N-0: 1 In the above polyatomic anion, what is the formal charge on: C? Answer

Answer 1

Bonding Electroy - Formal change = valence Electrons Nonbonding Nalence Electrous Formal charge = VE – NE – BE NE = Voelence electrons NE = Non bonding electrons BE = Bonding electrons T: SENZO) formal charge ons = VE – NE – BE = 6 - 2 - 6 = 6-2-3 = 6-5 In this structure, Sulphur has a love pair of electron means e non bonding electrons and It forms 3 bond with Nisou has 6 Bonding electrons Valence electrons in Sulphur is +6.

1-1 TiSEN-C: If formal change on N= VE - NE- BE = = 5-org = 5-4 valence electrons in Nitrogen = 6 Nitrogen formy 4 bonds so, it has & bonding electrons and it has not love pair of electron So, number of Nona bending electrons = 0 fis EN-C.T formal charge anc = VE-NE-BE Qe = 4 - 6 = -3 valence electrons in Carhan = 4 Carbon forms I band with Nitrogen so, it has 2 bonding electrons Carbon has 3 love pahes of electrons. So, number of non-valence electrons = 6 Iso Formal charge an S, N,C are 1, 1 and 3 respectivelift ī
