Study Notes

Carbon and Its Compounds: Hydrocarbons and Functional Groups

Carbon is one of the most diverse elements in nature due to its ability to form strong covalent bonds with other atoms, particularly with itself. This property leads to numerous carbon-based compounds, many of which are essential building blocks of life. One group of such compounds contains only carbon and hydrogen, known as hydrocarbons. These compounds can further be classified into two main types based on their chemical structure—alkanes and alkenes.

Alkanes and Alkenes

Alkanes consist solely of single bonds between carbon atoms while alkenes contain double bonds between some of their carbon atoms. Both classes have various members depending on the number of carbon atoms they possess. For instance, methane (CH₄) and ethane (C₂H₆), both alkanes, serve as simple examples. A more complex example of an alkane is hexane (C₆H₁₄), whereas another common compound, ethene (also called ethylene; C₂H₄), demonstrates alkene properties.

The simplest alkene is propene (propylene; C₃H₆) which has a bond angle of approximately 120° between the first two carbons. In contrast, ethyne (acetylene; C₂H₂) exhibits linear geometry with its central triple bond being perpendicular to the plane containing the hydrogen atoms.

Functional Groups

These fundamental units within organic molecules contain high electron density regions around specific atomic centers, resulting from different types of bonding environments and hybridization configurations. They play crucial roles in determining the reactivity patterns of organic compounds through their reactions with reagents like nucleophiles and electrophiles, affecting the overall stability of the molecular structures. Examples of functional groups include alcohols (-OH), carboxylic acids (-COOH), ketones (-C=O), and amines (-NH₂).

In summary, understanding hydrocarbons and functional groups is pivotal in grasping the vast realm of organic chemistry, where these components act as building blocks for countless natural products and synthesized materials.
