Four General Categories of Organic Reactions Organic reactions tend to fall into four categories: substitutions, additions, eliminations, rearrangements. Substitutions In a substitution reaction , one atom or group replaces another in a structure. This type of reaction is commonly observed in saturated hydrocarbons and aromatics. R- X an alkyl halide + Na + - OH R-OH + Na + X - H 2 O Ar- H an aromatic + Br 2 Fe Ar-Br + H Br The mechanisms of the above two substitution reactions are completely different.
