Reagent Identification
Reagents are chemical substances that are used to bring about a chemical reaction. The choice of reagents for a given transformation is influenced by a number of factors, including the selectivity, reactivity, and cost-effectiveness of the reagent.
The following table provides examples of organic transformations, their reactants and products, and the reagents needed to carry out each transformation:
| Transformation | Reactant(s) | Product(s) | Reagents |
|---|---|---|---|
| Nucleophilic substitution | Alkyl halide | Alcohol | Hydroxide ion |
| Electrophilic addition | Alkene | Alkyl halide | Hydrogen halide |
| Radical addition | Alkene | Alkyl radical | Radical initiator |
| Oxidation | Alcohol | Ketone | Potassium permanganate |
| Reduction | Ketone | Alcohol | Sodium borohydride |
