Nucleophilic substitution reactions are fundamental in organic chemistry, involving a nucleophile replacing a leaving group in a molecule. These reactions are key for creating diverse organic compounds, with mechanisms varying by the structure of the reactant. Factors like the leaving group's nature and the reaction conditions influence the reactivity and stereochemical outcomes, which are crucial for synthesizing enantiomerically pure compounds and extending carbon chains in complex molecules.
