(b) (i) Calculate the magnetic moment of Ti^(3+) and V^(4+) (ii) Draw all possible isomers of the complex [Co(en)_(2)Cl_(2)]^(+) and identify the optically active isomer. |

Answer» Solution :(b) (i) `TI(Z =22) Ti^(3+) 3d^(1)` `V(Z=23) V^(4+) 3d^(1)` `therefore mu = SQRT(1(1+2)) = sqrt(3) = 1.73 mu_(B)`. So they are paramagnetic (ii) 1. Cis `[Co(en)_(2)Cl_(2)]`  `[Co(en)_(2)Cl_(2)]^(+)` The coordination complex `[Co(en)_(2)Cl_(2)]^(+)` has three isomers TWO optically active cis forms and the optically inactive trans form.
