Carbon's Compounds: An Adventure into Organics, Hydrocarbons, and Functional Groups

Carbon is a remarkable element that forms the foundation of our world's living organisms. Its ability to bond with other elements in a variety of ways gives rise to an incredible array of compounds. We'll explore this realm through the lens of organic chemistry, focusing on hydrocarbons and functional groups, which together give us the rich tapestry known as carbon compounds.

Organic Compounds

Organic compounds are carbon-containing molecules that form the basis of living organisms. These compounds often contain hydrogen, but they can also contain other elements like oxygen, nitrogen, sulfur, and halogens. A defining characteristic of organic compounds is their ability to form long chains and intricate structures.


Hydrocarbons are organic compounds consisting only of carbon and hydrogen atoms. They are the simplest organic compounds and are classified into two main categories: alkanes and alkenes.


Alkanes are saturated hydrocarbons, meaning all the carbon atoms are bonded to the maximum allowed number of hydrogen atoms. They are typically straight or branched chains with the general formula C_nH_(2n+2). Alkanes are non-polar, making them hydrophobic and often volatile.


Alkenes are unsaturated hydrocarbons, meaning they contain carbon-carbon double bonds (C=C) and have the general formula C_nH_(2n). Alkenes are less stable than alkanes due to their double bonds, and they are more reactive. They can be further classified as alkadienes (with two double bonds) or alkatrienes (with three double bonds), and so on.

Functional Groups

Functional groups are specific arrangements of atoms within a molecule that give the molecule unique chemical properties. These groups can be attached to carbon atoms within an organic compound. The presence of functional groups allows us to classify and predict the reactivity and behavior of organic compounds.

Some common functional groups include:

  • Hydroxyl group (OH): Found in alcohols, phenols, and carboxylic acids.
  • Carbonyl group (C=O): Found in aldehydes, ketones, and carboxylic acids.
  • Amide group (-CONH2): Found in amides.
  • Ester group (COOR'): Found in esters.
  • Carboxyl group (-COOH): Found in carboxylic acids.
  • Amino group (-NH2): Found in amines and amino acids.


Isomerism is the phenomenon where two or more compounds have the same molecular formula but different structures resulting in distinct chemical and physical properties. In carbon compounds, isomerism is common and can be classified into structural, positional, and functional isomers.

  • Structural isomers: These isomers have different carbon skeletons, such as branched and straight-chain alkanes.
  • Positional isomers: These isomers have the same carbon skeleton, but the functional groups are in different positions, such as 1-bromobutane and 2-bromobutane.
  • Functional isomers: These isomers have different functional groups, such as butan-1-ol and butan-2-ol.

Carbon compounds are a diverse yet fascinating realm, offering an endless array of applications in pharmaceuticals, materials science, and energy production. The beauty and complexity of carbon compounds continue to inspire research, innovation, and discovery.

Delve into the world of organic chemistry by exploring carbon compounds, hydrocarbons, functional groups, and isomerism. Learn about the diverse structures, properties, and classifications of these compounds, which play a vital role in pharmaceuticals, materials science, and energy production.
