Naming Alkanes | IUPAC Nomenclature | 4.1 Organic Chemistry
After this lesson you will be able to…
- Learn the basic rules for naming alkanes, parent chains, and substituents.
- How to choose the parent chain when there are multiple chains of equal length.
- Using prefixes like di, tri, and tetra for multiple identical substituents.
- Breaking numbering ties using the lowest locators and alphabetical order.
- Naming rings as parent chains and handling single halogen substituents.
- Numbering rings with two substituents using alphabetical tie-breakers.
- Finding the lowest possible set of locators for tri-substituted rings.
- Naming molecules where the linear chain is longer than the attached ring.

Quiz: Naming Alkanes — Rules and Examples
FundamentalsAnswer each question based only on what was presented in the video lesson. No outside knowledge is needed. Read each question carefully before responding.
Practice: Naming Alkanes and Cycloalkanes
PracticeApply the IUPAC naming rules from the video to name the alkane or cycloalkane described in each problem. Show all steps: identify the parent chain, number it correctly, and build the full name. Problems increase in difficulty.
Advanced: IUPAC Nomenclature of Alkanes and Cycloalkanes
AdvancedThese challenging questions go beyond basic naming practice — expect multi-step reasoning, ambiguous structures, and scenarios that require you to apply, analyze, and evaluate IUPAC rules under exam-level pressure. Work carefully through each stem before selecting or constructing your answer.
