    Thank you. You are a lifesaver. Thank you for specifically 11:00, I've just not ever done a ring and was just totally lost.

    Please make English subtitles your videos. This makes learning easier for non-English speaking countries

    • @Leah4sci

      I'm confused. This video (almost all of my videos) has English captions. Be sure to turn them on in the lower right corner of the video player

    At 12:12 , why did C(CH3)3 take number 1 ? Its (C_C_C but the other one is C_C_S ) and S has a priority ?! 😢

    • @Leah4sci
      @Leah4sci  4 หลายเดือนก่อน

      In the Cahn-Ingold-Prelog priority system, we branch out from the chiral carbon one atom at a time and consider the direct points of contact of each 'branch'. The Carbon of C(CH3)3 is directly bonded to three other carbon atoms, while the Carbon that takes number 2 is directly bonded to only one other carbon and two hydrogens. In other words, the sulfur is just one spot too far away, or one spot removed from changing the order of the priority.

    i have a question is this a cis compound also ? 12:32
    so how many sterioisomers it has ? is it 8

    • @Leah4sci
      @Leah4sci  11 หลายเดือนก่อน +1

      I can tell you that this compound is not a cis compound, as the two substituents are drawn on opposite faces of the ring. That makes it a trans configuration. As for your other question, this is not exactly what this video was made to cover.
      Since I don't offer tutoring over social media, for help with questions like this and more, I recommend joining the organic chemistry study hall. Details: leah4sci.com/join or contact me through my website leah4sci.com/contact/

    for the last problem, why carbon bond to SH, H, CH2 and CH2 on the ring is chiral ?? it doesnt have 4 different group

    • @Leah4sci
      @Leah4sci  5 ปีที่แล้ว +1

      If you hit the same group you don't stop, instead you check what's next. I cover this in this video: leah4sci.com/r-and-s-configuration-for-lengthy-complex-substituents-2/

    Doesn't the 4th priority have to be on a dash???

    • @Leah4sci

      Yes, but that's where tricks come in

    Sound quality is not good, and echoing. Would you please record the sound in better quality. Thanks

    • @Leah4sci
      @Leah4sci  5 ปีที่แล้ว +1

      I'm sorry for that and thanks for letting me know. This is the recording of a live workshop and I was assured sound was ok, also sounds fine on my end so I wonder if perhaps it's your device? try it on another device and let me know if that's any better
