Definition

Organic Compounds are pure substances whose molecules are made up of 1 or more carbon atoms that are covalently bonded to other elements, most commonly hydrogen, oxygen, chlorine or nitrogen #ChemistryDefinitions

these compounds can be obtained from natural or artificial sources. e.g. citric acid found in citrus fruits is a carboxylic acid.

Understanding

organic chemistry is a branch of chemistry related to the study of structure, properties, reactions and preparation of organic compounds. in the study of organic compounds, it is important to classify the many compounds according to their similarities.

Sample

short chain alkenes/alkanes have 1-4 carbon atoms (ish)

  • they are usually in gaseous state

Important

unsaturated only refers to 1 or more carbon-carbon double bonds, there is no relation to double bonds between any other molecules

Important

every time you introduce a new double bond, must lose 2 hydrogen

represent anion first for organic
