Chem1B-81638-Fall19 RhCl] I AM * ? unpaired electron(s) Submit Request Answer Part B (Co(OH))" AEP OR? unpaired electron(s) Submit Request Answer Part C cis - [Fe(en), (NO),] V AED - O ?

Answer 1

- complex - [Rholo] Rh - atomic number of Rhodium Rh = us electronic configuration Rh]= ko u doss' Here in comple. cL carries al charge. - hence total -6. + 33 +3–6 = -3 Hence oxidation state of indiun - is- 33 ehat koud so I do system. Trillo) LH unpaired electronie complex, Hence para magnetic

- ) [co COH), cobalt atomic number = 2 sk Electronic_configuration [co] = [Ar] ad 7 us² Io complex oti carreies | Hence total -6 C لم +2-6= -4] Hence oxidation state of cobalt cot - [Ar] 3d7 us +2 dz system LALALA a Three unpaired complex hence electron in para maghetic

a cis [Fe (en) (NO2)2 ! Hexe en is bidentate ligand Fe atomic no. of Iron = 26. electronic configuration Fe = [ar] 3. Liga Here in complex (en) -ethylene dianine carries - charge. Hence total 4 Noz carries & Hence total --- charge +21 Eis fe cen) (NO2) I (34+2 t -altz Hence oxidation state of Pe=+3 Feat - Car] 3d us - ds_system - 1111 1111111 five unpaired electron Hence para magnetic in compless
