2020 P1 Q29 - Deducing Arrangement of Dative Bonds in Octahedral Complex

Let's take a look at 2020 A Levels H2 Chemistry Paper 1 Question 29.

2020 p1 q29 question

We are asked to deduce which diagram correctly shows the arrangement of the 6 coordinate or dative bonds in an octahedral complex of ruthenium.

From VSEPR (Valence Shell Electron Pair Repulsion) Theory under Chemical Bonding, we have learnt that a species with octahedral shape will have 6 bonds perpendicular to each other.

Check out the following video to learn more about using VSEPR to determine shapes of molecules.

There are 2 common ways to show octahedral molecules or complexes:

Therefore the answer to this question will be option A.
