Jessica Robins Lab 3: Properties of Organic Compounds Introduction Distillation is a physical process used to separate chemicals from a mixture by how easy they vaporize. The temperature rises unit it reaches the temperature of the lowest boiling substance in the mixture while the other contents of the mixture remain in their original phase (until the most volatile substance has all boiled off) as it’s heated. Hot vapor results and passes into a condenser and is then converted to a liquid

Use this packet and your book to answer the questions throughout this packet. Organic Nomenclature - Alkanes‚ Alkenes‚ Alkynes Naming organic compounds can be a challenge to any chemist at any level. Historically‚ chemists developed names for new compounds without any systematic guidelines. In this century‚ the need for standardization was recognized. For simple molecules‚ the nomenclature system worked out by the International Union of Pure and Applied Chemists (IUPAC) works well. For complex
