| Also Known As | SN1 reaction, SN2 reaction, electrophilic substitution, nucleophilic substitution |
What is Substitution Reaction?
A chemical reaction in which one atom or group in a molecule is replaced by another atom or group. Types include nucleophilic substitution (SN1, SN2), electrophilic aromatic substitution, and radical substitution. Common in organic chemistry for synthesizing new compounds.

Substitution reactions are used extensively in organic synthesis to introduce functional groups into molecules. Halogenation, nitration, and sulfonation of benzene are industrially important electrophilic substitutions. Pharmaceutical synthesis relies on nucleophilic substitution to build drug struc…
Substitution reactions may involve toxic reagents such as alkyl halides (carcinogens), concentrated acids, or hazardous nucleophiles. Many reaction solvents are flammable. Reactions should be conducted in fume hoods with appropriate safety measures.
