Substitution reactions typically yield

• A. A single product is formed
• B. No reaction occurs
• C. Two products are formed
• D. Only a polymer is formed

Answer: (C)

Substitution reactions involve replacing a leaving group with a nucleophile. As this replacement happens, the leaving group leaves to form its own product (usually an ion). The nucleophile then attaches to the substrate to give the substituted molecule. So, after the reaction there are two products: the new substituted compound and the leaving group in its ionic form. This applies to both SN1 and SN2 mechanisms, though the steps differ. It’s not just one product, nor is it a no-reaction situation, and polymer formation isn’t the typical outcome for simple substitution.
