Learn Organic Compounds is an interactive reference tool for exploring the major classes of organic compounds. Select a compound class to view its members with their functional groups, IUPAC names, structural formulas, common names, and real-world uses.
Compound Classes
Alcohols
Alcohols contain a hydroxyl group (-OH) bonded to a carbon atom. They are polar molecules that can form hydrogen bonds, making many of them miscible with water.
Key examples include methanol (wood alcohol), ethanol (drinking alcohol), and glycerol (glycerine used in cosmetics and food).
Aldehydes
Aldehydes contain a formyl group (-CHO) at the terminal end of a carbon chain. They are reactive compounds often used in synthesis and as preservatives.
Key examples include methanal (formaldehyde, a preservative) and benzaldehyde (almond oil essence, used in flavoring).
Ketones
Ketones contain a carbonyl group (C=O) positioned between two carbon atoms. Unlike aldehydes, they are not easily oxidized further.
Key examples include propanone (acetone, widely used as a solvent) and cyclohexanone (used in nylon production).
Carboxylic Acids
Carboxylic acids contain a carboxyl group (-COOH). They are weak acids and react with alcohols to form esters.
Key examples include ethanoic acid (acetic acid, the main component of vinegar) and citric acid (found in citrus fruits and used as a preservative).
Esters
Esters are formed from a carboxylic acid and an alcohol. They contain an ester group (-COO-) and are known for their pleasant, fruity aromas.
Key examples include ethyl ethanoate (ethyl acetate, a common solvent) and isopentyl ethanoate (banana oil, used in artificial flavoring).
Ethers
Ethers contain an oxygen atom (-O-) bonded to two carbon groups. They are relatively unreactive and commonly used as solvents.
Key examples include ethoxyethane (diethyl ether, historically used as an anesthetic) and methoxymethane (dimethyl ether, used as a propellant).
Amines
Amines contain an amino group (-NH₂) and are derivatives of ammonia. They are basic in nature and play an important role in biological systems.
Key examples include methanamine (methylamine), ethanamine (ethylamine), and phenylamine (aniline, used extensively in dye production).
Amides
Amides contain a carbonyl group bonded to a nitrogen atom (-CONH₂). They are found in proteins and synthetic polymers such as nylon.
Key examples include ethanamide (acetamide) and benzamide (used in pharmaceuticals and dye synthesis).

Frequently Asked Questions
What are organic compounds?
Organic compounds are chemical compounds containing carbon atoms, typically bonded to hydrogen, oxygen, nitrogen, or other elements. They form the basis of all living matter and are central to chemistry, biology, and industry.
What is a functional group?
A functional group is a specific arrangement of atoms within a molecule that determines its chemical properties and reactivity. Each class of organic compound is defined by its characteristic functional group.
How are organic compounds named?
Organic compounds are named following the IUPAC (International Union of Pure and Applied Chemistry) system. Names are based on the parent carbon chain length, the type of functional group, and the position of substituents.
What is the difference between aldehydes and ketones?
Both contain a carbonyl group (C=O), but in aldehydes it is at the end of the carbon chain (terminal), while in ketones it sits between two carbon atoms (internal). This difference makes aldehydes more reactive toward oxidation than ketones.
What is the difference between carboxylic acids and esters?
Carboxylic acids contain a free -COOH group and are acidic. Esters are formed when the hydrogen of the -OH in a carboxylic acid is replaced by a carbon group from an alcohol, giving the characteristic -COO- linkage.
