Answer» (B)`overset(III)([Co(NH_3)_6]Cl_3) and overset(IV)([Pt(NH_3)_5Cl])Cl_3` have different primary valencies but same number of ions. So same electrical conductance . Do not have same effective atomic number as in both complexes METALS have different atomic number. As there are three `Cl^-` ions out side the coordination sphere both will gives 3 moles of the precipitate of AgCl(WHITE). (C )`[Pt(NH_3)_2Cl_2] and (NH_4)_2 [PtCl_4]`. Pt is in +2 oxidation state so same primary valencies and same effective atomic number (84) and does not have same electrical conductance (former is NEUTRAL complex where as later ONE has 3 ions in aqueous solutons). No precipitate with `AgNO_3` as `Cl^-` ions in both complexes are in coordination sphere. (D)Both have Fe in +2 oxidation state so same primary valencies but have different number of ions.so different electrical conductance (former has 3 ions where as later one has 5 ions in aqueous solution). Both complexes have same effective atomic number (i.e. 36). |
