Naming Branched Chain Alkanes

Nomenclature Branched Chain Alkanes Tutorial Orgo Leah FischNaming Organic Compounds Series: Video 3
This tutorial video takes you through the steps of naming branched chain alkanes using the IUPAC naming rules. A branched chain alkane is an organic molecule that has smaller carbon chains sticking out in the middle rather than having all carbons connected in a single row. Video includes a number of practice problems from simple to tricky, single and multiple branches.

  1. Thank you for your videos!
    so to double check, at about the 4:30 mark…. even if other substituents have more carbons that will not give it higher priority to “first” substituent on the parent chain? (initially i thought it would be 2-methyl-5-ethylheptane)

  2. I loved it, great tutor

  3. very helful! best tutor ever! you are very good at explaining!!

    i finding difficult to select the parent chain rarer than its very helpful.thank you for presenting these videos.and your voice too very nice.

  10. Thanks so much your videos helped me study for an orgo test;p One of the things I never understood was whether the prefixes such as di or tri counted for the abc order so thank you;p

  11. Brittany Harry says

    I just wanted to let you know that I did not even think about highlighting the parent chain!! We recently learned about this in Organic 1 class and your method and ideas are very helpful! Thank you !!

  12. Thank You!!! Thank You!!! Thank You!!! :))))))))

  13. I appreciate the help !! I really needed to refreshen my memory !!! Thank you very very, very much !!!
