Chemistry plays a pivotal role in improving the quality of life by linking health with sustainability. In the field of health, organic chemistry contributes to the development of effective drugs, where chemical compounds are designed through addition and substitution reactions on alkanes and alkenes to create anticancer or anti-inflammatory treatments. These reactions allow scientists to produce precise and efficient molecules that meet patients’ needs. From a sustainability perspective, modern chemistry emphasizes green chemistry and reducing the environmental impact of chemical processes. For example, renewable resources can be used to produce biodegradable polymers, reducing plastic pollution and promoting a circular economy. Carefully selected organic reactions also contribute to the production of medical materials and pharmaceuticals with minimal waste and higher efficiency, balancing scientific advancement with environmental preservation. In short, the power of chemistry lies in its ability to combine health and sustainability through innovations in organic reactions, transforming them into practical solutions for the future.
