Final answer:
Substitution reactions have several real-life applications in organic chemistry, cooking, and industry. They are used in the synthesis of drugs, production of polymers, and cooking processes.
Step-by-step explanation:
In a substitution reaction, one or more atoms replace another atom or group of atoms in a molecule. This type of reaction is commonly observed in organic chemistry. For example, halothane, an alkyl halide, is used as a general anesthetic for surgical procedures. It undergoes a substitution reaction where a halogen atom replaces a hydrogen atom in the molecule.
Another real-life application of substitution reactions is in cooking. When you add salt to a dish, the chloride ions in the salt can undergo a substitution reaction with the hydrogen ions in the food, resulting in the release of chlorine gas.
Similarly, in the industry, substitution reactions are used for various purposes such as producing pharmaceutical drugs, making polymers, and synthesizing new compounds. For instance, the synthesis of nylon involves the substitution reactions of monomers to form strong and flexible fibers.
