Interpret Venn Diagrams
Each circle of the Venn diagram represents a criteria – those being ‘Scalability’, ‘Greenness’ and ‘Wide utility’
The ideal reagent will have all three characteristics and so appear in the middle (green area), whereas some reagents have one of the traits but none of the others and some are a mix of two but not the third.
Placements within the Venn can change with many variables (solvent, catalyst, treatment of wastes etc). As outlined they are a good estimate but not final with discussion actively encouraged.
