Question

(a) For the complex $\left[Fe\right(H_{2}O{)}_6{]}^{+3}$, write the hybridisation, magnetic character and spin of the complex. (At. number : Fe = 26)
(b) Draw one of the geometrical isomers of the complex $\left[Pt\right(en{)}_{2}C{l}_2{]}^{+2}$ which is optically inactive.

Answer 1

(a) Hybridisation-$s{p}^3{d}^2$, magnetic character- paramagnetic and have octahedral geometry.

(b) The geometrical isomer is shown in the diagram. Trans isomer of $\left[Pt\right(en{)}_{2}C{l}_2{]}^{+2}$ shows no optical activity.
