Study Notes
Carbon Compounds
- Carbon is a versatile element that forms a wide range of compounds.
- Organic compounds are made up of carbon and are found in various materials, such as foodstuff, fibers, paper, medicines, wood, and fuels.
Classification of Compounds
- There are two main types of compounds: organic and inorganic compounds.
- Except for materials fabricated from metal and glass/soil, most other materials are made up of organic compounds.
- Carbon is the essential element in all organic compounds.
Properties of Carbon Compounds
- The melting and boiling points of carbon compounds are generally lower than 300°C.
- Carbon compounds are bad conductors of electricity.
- The intermolecular attractive forces in carbon compounds are weak.
Bonds in Carbon Compounds
- Carbon compounds lack ionic bonds, which means the chemical bonds in carbon compounds do not produce ions.
- The chemical bonds in carbon compounds are different from ionic bonds found in ionic compounds.
Examples of Carbon Compounds
- Methane (CH4) has a melting point of -183°C and a boiling point of -161°C.
- Ethanol (CH3CH2OH) has a melting point of -117°C and a boiling point of 78°C.
- Chloroform (CHCl3) has a melting point of -64°C and a boiling point of 61°C.
- Acetic acid (CH3COOH) has a melting point of 17°C and a boiling point of 118°C.
