This last and final topic lightly introduces generalized concepts associated with the advanced topic of organic chemistry. Often, college-level chemistry begins with a full semester of inorganic chemistry (Chem I) – preceding a semester of organic chemistry (Chem II). Students become acquaint themselves with the importance of carbon (C). Various formulas related to Alkanes and their naming conventions are touched-upon. Contrasts and comparisons of Alkenes and Alkynes are briefly examined. Last, a few conventions for naming Aromatic compounds are introduced. This topic does not aim for application or higher-level considerations of the subject-matter – rather, students should strive to become initially familiar with basic ideas and concepts preparing them for more advanced pursuits at a collegiate level.

Compare Contrast and Debate
Background: Alkenes are hydrocarbons that contain one or more double bonds, while alkynes contain one or more triple bonds. The naming conventions for these compounds are similar to those for alkanes.
- Alkenes and alkynes are named by identifying the longest chain that contains the double or triple bond.
- The chain is numbered to minimize the numbers assigned to the double or triple bond.
- The suffix of the compound is “-ene” for an alkene or “-yne” for an alkyne.
- Position A: Emphasis should be on the naming convention first … then the type of bond and structure.
- Position B: Emphasis should be on the type of bond and structure first … then by the naming convention.
