SAMPLE Chemistry

organic compounds, ranging from the familiar methane in natural gas to the complex structures found in proteins and plastics. Classically categorized into alkanes, alkenes, and alkynes, hydrocarbons serve as the fundamental building blocks for more intricate organic molecules.

Aromatic Hydrocarbons

Alkanes

Alkenes

Alkynes

Characterized only by single bonds between carbon atoms C–C . Alkanes are relatively non-reactive and are excellent fuels.

Characterized by having at least 1 double bond C=C .

Characterized by having at least one carbon-carbon triple bond C≡C .

Aromatic hydrocarbons, also known as arenes, consist of carbon atoms arranged in planar, cyclic structures.

Notable

● Structural representation in chemistry refers to the graphical depiction of a molecule’s arrangement, indicating the connectivity of its atoms and the type of bonds between them.
