Introduction to Organic Chemistry and Hydrocarbons A definition of organic chemistry as the study of carbon-based compounds. An explanation of what a hydrocarbon is, using examples of butane and butanol. 2. The Alkane Homologous Series An introduction to alkanes as the simplest type of hydrocarbon. A look at the structure and formula of the first four alkanes: methane, ethane, propane, and butane. A definition of a homologous series. 3. The General Formula for Alkanes An explanation of the general formula for alkanes: CnH2n+2. A demonstration of how to use the general formula to find the molecular formula of any alkane, using propane and octane as examples. 4. Saturated Compounds A definition of saturated compounds as molecules containing only single covalent bonds. The difference between saturated alkanes and unsaturated alkenes. ** CHAPTERS ** 0:00 Introduction 0:14 What is Organic Chemistry? 0:53 What are Hydrocarbons? 1:17 Alkanes 2:05 Homologous Series 2:16 The General Formula for Alkanes 3:44 Saturated Compounds ** PLAYLISTS **    • KS3 Biology      • KS3 Chemistry      • GCSE Maths (9-1)      • GCSE Biology (9-1)      • GCSE Chemistry (9-1)      • GCSE Physics (9-1)      • A-Level Biology   #GCSE #Chemistry #study #revision #school #exam #AQA #OCR #Edexcel #IGCSE
