Organic compounds are vast and diverse, but they can be categorized into distinct groups based on their functional groups and structural features. Here are four major types of organic compounds, along with their characteristics and examples:

1. Hydrocarbons

Definition: Compounds composed solely of carbon (C) and hydrogen (H) atoms.

Types:

• Alkanes: Saturated hydrocarbons with single bonds (e.g., methane, CH₄; ethane, C₂H₆).
• Alkenes: Hydrocarbons with at least one double bond (e.g., ethylene, C₂H₄; propylene, C₃H₆).
• Alkynes: Hydrocarbons with at least one triple bond (e.g., acetylene, C₂H₂).
• Aromatic Hydrocarbons: Contain benzene rings (e.g., benzene, C₆H₆; toluene, C₇H₈).

Uses: Fuels, plastics, solvents, and industrial feedstocks.

2. Oxygen-Containing Compounds

Definition: Organics with oxygen (O) in their structure, often in functional groups like -OH, -COOH, or -O-.

Types:

• Alcohols: Contain a hydroxyl (-OH) group (e.g., ethanol, C₂H₅OH; glycerol, C₃H₈O₃).
• Carboxylic Acids: Have a carboxylic acid (-COOH) group (e.g., acetic acid, CH₃COOH).
• Ethers: Feature an oxygen atom bonded to two carbon atoms (e.g., diethyl ether, C₄H₁₀O).
• Esters: Formed by condensation of acids and alcohols (e.g., ethyl acetate, CH₃COOCH₂CH₃).

Uses: Pharmaceuticals, fragrances, solvents, and biodegradable materials.

3. Nitrogen-Containing Compounds

Definition: Organics with nitrogen (N) atoms, often in amines, amides, or nitro groups.

Types:

• Amines: Contain amino (-NH₂) groups (e.g., ammonia, NH₃; methylamine, CH₃NH₂).
• Nitro Compounds: Have nitro (-NO₂) groups (e.g., nitroglycerin, C₃H₅N₃O₉).
• Cyanides: Feature a cyano (-CN) group (e.g., acetonitrile, C₂H₃N).
• Bioactive Compounds: e.g., alkaloids (caffeine, nicotine), amino acids (glycine, alanine).

Uses: Drugs, dyes, explosives, and agricultural chemicals.

4. Carbohydrates

Definition: Polyhydroxy aldehydes or ketones, or their polymers.

Types:

• Monosaccharides: Simple sugars (e.g., glucose, C₆H₁₂O₆; fructose).
• Disaccharides: Two monosaccharides linked (e.g., sucrose, C₁₂H₂₂O₁₁).
• Polysaccharides: Long chains of monosaccharides (e.g., starch, cellulose, glycogen).

Uses: Energy storage, structural components in plants (cellulose), and dietary fiber.

Key Differences

Type	Key Feature	Examples
