Description
Test your knowledge of organic chemistry compounds by naming and drawing the structures of methane, ethane, ethene, ethanol, ethanoic acid, and their reaction products as per topic 14.4-14.6. Remember the prefixes for compounds with different numbers of carbons (Metho, Etho, Propo, Buta).
