Question

2.(1) What does it mean when we say a transition metal complex (or a molecule) is chiral? 3.(3) Give the name or formula, as appropriate, for: a) [Co(CO)s]CO3 b) Ks[Fe(CN) 6] c) diaquabis(ethylenediamine)chromium(II) nitrate 4.(3) Give the coordination number, geometry, and hybridization of cobalt in [Co(NO2)2(en)2]2 5.(5) Draw all possible isomers of [CrNH)h(en)FJ. Label them as either geometrical or optical.

Answer 1

Ans 2 :

Whenever we say a molecule or transition metal complex is chiral , it means that the molecule is not superimposable on its mirror images.

Chirality can be considered as geometrical property of such molecules. The presence of a chiral or asymmetric carbon centre contributes to the chirality of the molecules at large.

When the carbon center is bonded to four different atoms or groups of atoms , it called as chiral. This causes the molecule or complex to be chiral too.
