'''Organic compounds''' are [[chemical compound|compound]]s with [[carbon]]. Almost all organic compounds contain [[hydrogen]] besides carbon. Many contain [[oxygen]] too. They are usually [[covalent compound]]s. |

People believed that only living things could make organic compounds and "dead" things (such as [[mineral]]s) could make inorganic compounds. However, Friedrich Wöhler proved this wrong because certain compounds in [[urine]] were thought to be inorganic, but urine came from a living thing. |

One way of showing the [[molecule]] is by drawing its structural formula. Because molecules can have complicated structures, people have made ways to show them in simple language. The latest way of showing organic compounds is the [[line-angle formula]]. This is based on Carbon atoms; each atom, including carbon atoms, is connected by a line to each atom that it is covalently bonded to. One line means a [[single bond]], two lines means a [[double bond]] and so on. |

Because there is in an infinite number of possible organic compounds, language is needed to give a unique name to each one. The International Union of Pure and Applied Chemistry, or [[IUPAC]], made a system for doing this. Although an IUPAC name makes every single possible molecule unique, the names are often long and complicated, so in everyday life, ''trivial'' names--unofficial but widely understood names--are used, such as the Trivial names Paracetamol, Tylenol, and Acetaminophen, which are used for a compound whose IUPAC name is ''N-(4-hydroxyphenyl)acetamide''. |
