All Chapters Video 3.1 IUPAC Basics and Naming Alkanes Chapter OutlineChapter Quiz Question? Ask Dr. Mike! Lesson Summary When naming alkanes: 1. Find the parent chain, the longest carbon chain. If two possible parent chains have the same length, but different substituent numberings, pick the one with the smaller substituent number at the first point of difference. 2. Count the number of carbon atoms in the parent chain and match that number to the name from our earlier chart (methane, ethane, propane, etc.) 3. Identify and number the substituents (appendage dangling off the parent chain) in whichever direction gives them the lowest number. 4. Write the name as a single word with the substituents in alphabetical order. Example: 3-ethyl-4,4-dimethylheptane Lesson 3.1 IUPAC Basics and Naming Alkanes 3.1 IUPAC Basics and Naming Alkanes 3.1 Quiz Video Solution 3.2 Naming Cycloalkanes and Alkyl Halides 3.2 Quiz Video Solution 3.3 Naming Alkenes 3.3 Quiz Video Solution (Pt. 1) 3.3 Quiz Video Solution (Pt. 2) 3.3 Quiz Video Solution (Pt. 3) 3.4 Naming Alcohols, Ethers, and Amines 3.4 Quiz Video Solution (Pt. 1) 3.4 Quiz Video Solution (Pt. 2) 3.5 Naming Aldehydes and Ketones 3.5 Quiz Video Solution 3.6 Naming Carboxylic Acids and Derivatives 3.6 Quiz Video Solution 3.7 Naming Aromatics 3.7 Quiz Video Solution 3.8 Naming Polyfunctional Compounds 3.8 Quiz Video Solution (Pt. 1) 3.8 Quiz Video Solution (Pt. 2) Instructor Dr. Mike Christiansen Dr. Christiansen is a chemistry professor at Utah State University and has a PhD in organic chemistry.
