Synthesis Reactions

Definition

Synthesis reactions, also known as combination reactions, are chemical reactions in which two or more reactants combine to form a single product. This type of reaction is represented by the general equation: A + B → AB

Key points

  1. Formation of a new substance: Synthesis reactions result in creating a new compound or molecule from simpler reactants.

  2. Energy absorption: These reactions often require an input of energy, typically in the form of heat or light, to initiate the reaction.

Examples

Common examples of synthesis reactions include the formation of water (2H2 + O2 → 2H2O), the synthesis of ammonia (3H₂ + N₂ → 2NH₃), and photosynthesis (6CO2 + 6H2O → C6H12O6 + 6O2 + 6H2).
