  1. This video helped clarify my questions on the structures. Thank you!

    Regarding 4-(1-methylethyl)-octane couldn’t you drop the 1 as that’s the only place the methyl group can go? If in doubt is it always best to add a number?

    What do you use as reference? I went to IUPAC website but didn’t find it very useful.

    I like your videos. To the point.

      I’ve seen it named without a number. I personally would keep the number to avoid any potential confusion

  3. Much more interesting and understandable than a 4 roomed packed class.
    Thank u for this video, I was having a trouble in understanding this topic.
    Well now I am surely getting 6 marks in my finals..

  4. It’s not 4-(ethyl-1-methyl) because of the alphabetical rule?

    • Be careful Clarice. Ethyl is considered the parent of the branch and so is not alphabetized with the substituents ON the branch
