  1. Hi Leah,
    I am slightly confused. For the molecule cyclohexanecarboxylic acid, is the carboxyl group considered a substituent group? In that case, should it not be carboxycyclohexane? Also, my sources tell me that the prefix of an aldehyde is alkanoyl so I’m confused. If you can clear things up, that would be awesome.
    Once again, thank you so much for these awesome videos!

    • There are different conventions to naming these strange groups on rings. carboxycyclohexane makes the ring priority but it’s the carboxy. alkanoyl is a less common abbreviation for aldehyde, as is formyl

  2. With the 5-chloro-2-methyl-3-hexenoic acid don’t you have to specify that the alkene part is E?
