Overview

Organic compounds containing only carbon and hydrogen are called hydrocarbons. The main families covered are alkanes, alkenes and alkynes. Alkanes are saturated hydrocarbons with only single bonds, alkenes contain a carbon-carbon double bond, and alkynes contain a carbon-carbon triple bond. Alcohols

Key Concepts

Alkanes are saturated hydrocarbons and

Alkanes are saturated hydrocarbons and are also referred to as paraffins. Their general formula is C_nH_{2n+2}. They contain only single covalent bond

Methane is a colourless

Methane is a colourless, odourless and tasteless gas. Natural gas contains about 85% methane, and its density at STP is 0.71 g/L. It has tetrahedral s

Methane and ethane undergo substitution reactions

Methane and ethane undergo substitution reactions where hydrogen atoms are replaced by halogen atoms. Methane reacts slowly with iodine and the reacti

Alkenes are unsaturated hydrocarbons containing one

Alkenes are unsaturated hydrocarbons containing one or more carbon-carbon double bonds. Their general formula for one double bond is C_nH_{2n}. Ethyle

Ethene undergoes addition reactions because

Ethene undergoes addition reactions because the double bond can break and allow new atoms to attach. It adds hydrogen to form ethane, halogens to form

Learning Objectives

  • Identify alkanes, alkenes, alkynes, alcohols and carboxylic acids by their functional groups and general formulas.
  • Explain the special properties of methane, ethane, ethene, ethyne, methanol, ethanol and acetic acid.
  • Write balanced equations for important preparations, combustion, addition, substitution, oxidation, esterification and fermentation reactions.
  • Understand why unsaturated compounds undergo addition reactions more easily than saturated compounds.
  • Relate laboratory preparations to industrial and daily-life uses of common organic compounds.
