Find the total number of complexes / species which are paramagnetic. (a) [Co(NH_(3))_(6)]^(3+),""(b) [Co(H_(2)O)_(6)]^(3+), (c ) [Cr(NH_(3))_(6)]^(2+),""(d) [CoF_(6)]^(3-), (e ) K_(3)[PtCl_(3)(C_(2)H_(4))],""(f) [Mn(NH_(3))_(6)]^(2+), (g) [Fe(NH_(3))_(6)]^(2+),""(h) NO_(2), (i) ClO_(2),""(j) [Pt(NH_(3))_(2)Cl_(2) |

Answer» (c )`[CR(NH_(3))_(6)]^(2+),Cr^(2+),3d^(4),SP^(3)d^(2)` hybridisation, complex (d) `[CoF_(6)]^(3-) Co^(3+),3d^(6),sp^(3)d^(2)` hy7bridisation, there will be FOUR unpaired electrons (e )`K_(3)[PtCl_(3)(C_(2)H_(4))]` diamagnetic (f) `[Mn(NH_(3))_(6)]^(2+) 3d^(5)`,5unpaired electrons, (paramagnetic).  (g) `[Fe(NH_(3))_(6)]^(2+)` paramagnetic (4 unpaired electrons) |
