Identify the functional groups or structural features in each molecule that could influence reaction rate. For example, aromatic rings, amine groups, or branching in alkanes.
Consider the type of reaction each molecule might undergo. Aromatic compounds like benzene (first image) typically undergo electrophilic substitution reactions, while amines (second image) can participate in nucleophilic substitution or addition reactions.
Evaluate the steric hindrance in each molecule. Highly branched alkanes (fourth image) may react slower due to steric hindrance compared to linear or less branched alkanes (third image).
Assess the electronic effects. Electron-donating groups, such as the amine group in the second image, can increase the reactivity of a molecule by making it a better nucleophile.
Compare the overall reactivity based on the above factors. Molecules with less steric hindrance and favorable electronic effects are likely to react faster.
