Carbon\u2019s unique ability to form stable, covalent bonds with itself and other elements makes it the backbone of millions of natural and synthetic compounds. Organic chemistry is foundational to fields such as biochemistry, pharmaceuticals, materials science, petrochemicals, and industrial chemistry. Without it, we would lack modern drugs, plastics, fuels, and countless everyday products.<\/span><\/p><p><span style=\"font-weight: 400;\">The study of organic compounds ranges from simple molecules like methane to complex macromolecules such as proteins, DNA, and synthetic polymers.
