Study Notes
Chemical Compounds
- Chemical compounds are broadly divided into organic and inorganic compounds
- Organic compounds primarily contain carbon and hydrogen, plus nitrogen, oxygen, sulfur, and other elements
- Hydrocarbons are compounds of carbon and hydrogen
- Hydrocarbons are classified as alkanes, alkenes, and alkynes
Hydrocarbons
- Alkanes (paraffins) have the general formula CnH2n+2
- Alkenes (olefins) have the general formula CnH2n
- Alkynes have the general formula CnH2n-2
Inorganic Compounds
- Inorganic compounds do not contain carbon (except oxides of carbon, carbonates, and hydrogen carbonates).
- Inorganic compounds can be classified as oxides, acids, bases, or salts
- Oxides are binary compounds containing oxygen and an element (metal, non-metal, or metalloid)
- Oxides are classified as acidic or basic depending on their properties
- Acidic oxides are non-metallic oxides that react with water to form acidic solutions
- Basic oxides are metallic oxides that react with water to form basic solutions
Acids, Bases, and Alkalis
- Acids are compounds that release hydrogen ions (H+) when dissolved in water
- Alkalis are substances that release hydroxide ions (OH-) in aqueous solution
- Bases are compounds that neutralize acids to form salt and water
- Alkalis are a type of base
- Indicators are substances that change color to show whether a solution is acidic or basic
Neutralization
- Neutralization is the reaction of acids with bases to form salt and water
- Neutralization is important in daily life (home, health, agriculture)
- Salts are compounds containing positive ions from bases and negative ions from acids
- Names of inorganic compounds can be deduced from a set of rules
