SN1 reactions proceed through a carbocation intermediate, while SN2 reactions occur in a single concerted step without any intermediate formation. SN2 has a complete configuration inversion. If the alkyl halide is optically active in the SN1 reaction, the result is a racemic mixture. Nucleophile assaults occur from both the backend and the front side of the SN1 reaction.\"\n\t\t\t\t\t\t\t\t\t}\n\t\t\t}\n\t\t\t,\t\t\t\t{\n\t\t\t\t\"@type\": \"Question\",\n\t\t\t\t\"name\": \"What are SN2 reactions used for?\",\n\t\t\t\t\"acceptedAnswer\": {\n\t\t\t\t\t\"@type\": \"Answer\",\n\t\t\t\t\t\"text\": \"SN2 reactions are used in organic synthesis to introduce various functional groups into organic compounds.
