I. INTRODUCTION Hydrocarbons are compounds that contain only carbon and hydrogen atoms. Methane (CH4) and ethane (C2H6) are one of the major examples of hydrocarbons. They also belong to a subgroup of compounds called alkanes. ALKANES are hydrocarbons that do not have multiple bonds between carbon atoms, and we can indicate this in the family name and names for specific compounds by the –ane ending. Other hydrocarbons may contain double or triple bonds between their carbon atoms. ALKENES contain at least one carbon-carbon double bond, and this is indicated in the family name and names for sp...
