Interpretation:
The colour of Cr+3 (aq) cation should be explained in comparison to the colourless Y+3 (aq.) cation.
Concept introduction:
As per crystal field theory, the colour in complex compound can be because of various reasons in which d-d transition of electrons are most common.
The different colours of similar metal ion complexes can be because of the difference in the ligands attached and the range of their absorptions.
To explain the colour of any complex or ion, the colour wheel is used. If a compound absorbs a particular colour of any range on the colour wheel then the colour just opposite to the wheel will be the colour shown or reflected by the compound.
Also, if the colour of compound is given then the absorption range can be obtained by using opposite colour of the colour wheel.
The wheel can be shown as:

- What would be the best choices for the missing reagents 1 and 3 in this synthesis? 1. PPh3 3 2. n-BuLi • Draw the missing reagents in the drawing area below. You can draw them in any arrangement you like. • Do not draw the missing reagent 2. If you draw 1 correctly, we'll know what it is. • Note: if one of your reagents needs to contain a halogen, use bromine.
