    *@ **7:24* I'm a bit confused because you said previously that the Br group must have the least number. But in this example, you're counting from the methyl group, why is that? When I counted from the Br group, I got the substituents being 3-chloro and 4- methyl, so the name I got was *1- bromo, 3- chloro- 4 methyl cyclohexane.* Is that name wrong?
    *@**11:10* could it also be named as *2, 2- chloro methyl propane?* Being that, there is 2 substituents on the same carbon?

    • @Saisei99
      @Saisei99 Год назад

      For ur first Q it's wrong ... Cause first u hv to be sure that the addition of the numbers in iupac should be least
      1 - bromo 3 chloro 4 methyl cyclohexane here it is 1+3+4=8
      But correct answer is
      4 bromo 2 chloro 1 methyl cyclohexane
      4+ 2+1 = 7

    8:12 for the question in that timestamp, if we arrange the numbers that way, it becomes in descending order and u said in a previous video that it's better to have the numbers in ascending order after putting them in alpha order.

    So when naming these compounds, what is the true priority? You make it sound like it is alphabetization, but then you also make it sound like it's the numbering (increasing)

    • @taithollis615
      @taithollis615 4 года назад +3

      Alphabetization and then ascending number order

    • @fatimasaleemaziz
      @fatimasaleemaziz Год назад

      Yeah one thing my teacher does is that she writes the priority list side by side when we start any functional group

    @michalischronakis3129 3 года назад +1

    Actually, when there is a functional group and a multiple bond, you have to prioritize your numbering based on the group first. So the one around 4 mins is actually 2-fluoro-5-hexene

  • @su1eman282
    @su1eman282 5 лет назад +1

    I think there is a mistake -- at 7:25 you state that 1,2,4 is the best way to count it, giving the order: 1-methyl-2-chloro-4-bromo. but then at 7:55, you end up just putting it in alphabetical order anyways...

    • @toshitall261
      @toshitall261 5 лет назад +1

      Best way to count to reduce the overall sum of the numbers used, but doesn't affect the alphabetical order

    • @williamwilliamson830
      @williamwilliamson830 4 года назад +2

      its always going to be in alphabetical order when writing the name, it doesn't matter which number accompanies the substituent when writing the name as you should have established the lowest number group while counting the carbons. So always count the carbons to achieve lowest number groups for substituents THEN put them in alphabetical order for the name.

    I don't understand the 3-element style. I thought we're supposed to "count" the elements alphabetically, so shouldn't bromine come first then methyl and then chlorine

    • @itsnajeb.2350
      @itsnajeb.2350 2 года назад

      should be lower number since starting with bromine would give 1,3,4 unlike with methyl which would give you 1,2,4

  • @samho2137
    @samho2137 Месяц назад

    I want to ask when there is a double bond and a halogen/methyl group, then do I always name the molecule such that the double bond is at lower position. But I saw in my textbook example like 2-methylhex-3-ene but i think it is 5-methylhex-3-ene as alkene need to be at a lower position

    • @paysonkeown2960
      @paysonkeown2960 Месяц назад

      We number it just to give the alkene the lowest number we can get for the alkene. If there are then other groups like in your example and they both have the same number on the alkene, then we look to get the lower number for the groups
