Definition: Stereochemically is a term used in the field of chemistry to describe a chemical reaction that involves two or more reactants being chemically combined. This process typically results in the formation of a single product, which can be a solid, liquid, gas, or solution. For example, if we have two reactants, carbon dioxide (CO2) and water vapor (H2O), this reaction is described as stereochemically: 1. Carbon dioxide reacts with water vapor to produce CO
