Verdict
The clearest difference is in-app purchases: Molecular Formula Generator at none against Functional Groups's 1. Molecular Formula Generator also leads on iOS requirement (7.0 vs 15.0). Functional Groups's advantage is update cadence (every 4 months vs every 16 months) and ratings volume (21 vs 3). On price, rating, ads and device support there is nothing between them.
