protip: if you dont have a modelling kit, i used toothpicks and jellybeans
Thank you, this is a money saver
I also use tooth picks and clay
Genius
great idea!
Cant believe how you just gave me clarity on this a day before my exams... Blessings to you
Femi Adelekan what happened on the exam 😅😅
Queen 97 lol aced it
Congratz man ^^
You're very welcome, and thanks for the kind words!
Awesome!
My chemistry lecturer sent me here. I love this video
Glad you liked it!
Unilorin???
@@David-by2ko Lol.. yeahhh😂, wait did a lecturer send you here also???
@@oreoluwafalana1835 yes🤣, so funny
Hey heyyy, how was the exam tho???😗
Leah you are the only person I watch on CZcams for any orgo help. You're simply the best at what you do!!
She’s literally the best i passed well my organic chem exams last year because of her
aw thank you! I am honored and strive to keep living up to your expectations all semester
@@Leah4sci Jesus loves you ❤️ Please turn to him and repent before it's too late. The end times described in the Bible are already happening in the world.
Omgg this made things so clear!! You really have a gift for explaining!! It's easy to be a professor, but to be able to explain something highly technical to another person, and in layman's terms, is a real talent!! Better than my lecturer who forgot to tell us what's the meaning of a thick solid bond and a dashed bond 💔
Oh wow, I'm so happy to hear that I helped clear things up for you!
I feel like with these clear videos and materials on this channel everyone can master OChem. I am trying to prepare for MCAT by self studying using this chamnel and I don't feel I am missing anything.
Glad to hear it! Check out my MCAT channel, too: leah4sci.com/MCATyoutube
Dear Leah,
I'm currently in high school, and you cant imagine how much helpful these videos are !!😭❤
THANK YOU SO MUCH ✨
You're so welcome!
You are born to teach!!! I LOVE your style!!! Not only do you explain concepts, but you also help those like me who can't visualize anything to finally be also to do so!!!
Thank you so much!
Thanks for your kind words, happy to help!
I thought I'd never get the hang of this but I finally did ...you're amazing!!! Thank you
You're very welcome! Glad i could help!
thank u for making these. trying to learn 3 chapters of material in two days because i had a manic episode and missed out a ton. :/
I'm so happy I was able to help you when you needed it; take care of yourself!
THANK YOUUUUUUUUUUUUUUUU! MY PROF MADE THIS SO MUCH HARDER THAN IT HAD TO BE. you're awesome
You're so welcome, I'm glad I could clear it up for you!
You are the best.. Chirality was always a centre of confusion for me but now everything is crystallized in front of me.. Thanks from the left ventricle of my heart.
Haha you are very welcome!
I already watched nomeclature video and I had a great belief in your teaching that make understood about stereochemistry. You done it.... Thanks a lot....A great salute ma'am
You're very welcome, happy to help!
I watched all your relevant videos before my first orgo exam and got 100%, so here I am again! :D
Ps. thank you so much! These videos are super helpful and clear.
Thank you for your wonderful feedback and great job on your exam! You're welcome :)
assalamalaikum...ur video lectures nd method of teaching has generated an intrst in me of organic chemistry....i wil pass my Msc v easily now...thnx alot
You're very welcome!
oh my God, you're just amazing :-) i'm really happy that i found you
Thanks for your kind words :)
Exzactly!
I have been watching your videos for a long time now. Your explanations are always amazing and you make my concepts very clear. Thanks a lot
You're very welcome, happy to help!
Any person having zero knowledge Of StereoChemistry can understand this. Knowing English and basic Chemistry is prerequisite! Great! 👍
Thanks for the feedback! Glad to help! :)
Great explanation. So many other video authors forget how effective it is to use the simplest model, a ball and stick, and then by hand show the difference in it's mirror image. If you have to imagine it going into or out of the plane, why use a video at all? as some others are doing.
Glad I could help :)
I really adore how you explain organic chemistry.. which is not only this video but also ur books on online.. Much gratitude to you. May good Lord uplift ur carrier.
Thanks for your kind words!
Owemji I've watched soooo many videos I've literally fallen for you 😞
aww, thanks! Orgo will do that to you!
I always had problems in understanding my lecturer in terms of stereochemistry but till today after I watched your video,it is really mind opening and easily understandable ....... thank u
You're so very welcome, happy to help clear things up!
Our professor recommended this channel for further reading.
Awesome, tell your professor I said thanks!
thank you 💙💙💙last time i study from your video and i had a full mark so i am bake now to study the final exam 💙💙💙
Awesome! Let me know how it turns out!
@@Leah4sci i got -A
I'm so proud of myself and happy to know your channel thank you 💜
Fun Fact 😺: When leah joined elementary schools she teached her teacher 🤭❤️.
Lol, no, but thanks for the compliment!
you explain this difficult topic into Easiest and very interesting way...😄😃
Happy to help!
Sending your awesome video to my students in AICE Chemistry - great job! I'm super jelly! #ChemTeachersRule
Aww thanks for sharing!
Leah your teaching style is awesome.I also want to be like you
I wish you good luck on your beautiful ambition
Aww thanks for the kind words!
This is the best video ever
Wow! thanks! :)
Im grateful to finally found your awesome videos! I love the way you explain, thank you! Wish me luck, my Orgo paper is in two days... phewhh..
Hope it went well for you, so happy to help!
Seriously It was so good ..... And u r honest too...
Glad you liked it!
Once again you are awesome. All your O'chem videos are just..... .. I have no further comments. lol
Aww thanks!
u r amazing😊😄u explained each n everything so clearly.... best explanation ever
Thank you! Glad you liked it!
hey sis! thank you so much, now I can survive my exam somehow
You're very welcome, happy to help!
I hate reviewing chemistry, but reviewing Ochem is bearable watching your videos. Thanks!
I'm so glad to hear that, happy to help!
Mam you are awesome .......
I don't know how to thank you
Aww, you're so welcome!
Has anyone ever told you that you're a legend ?

Thanks for the video 😇
You're very welcome!
hello ! a quick question,
if a molecule is superimposable does it has to be achiral ?
and if a molecule is not superimposable does it has to be chiral ?
To talk about being superimposable means to compare two structures to see if they align with each other.
If a molecule is chiral, that means its mirror image can NOT be superimposed on the original structure. If a molecule is achiral, that means its mirror image CAN be superimposed on the original structure.
So helpful. Thanks!
You're welcome!
Hi! At 9:47 you say "if it's not chiral, it will not have a mirror image." Can you explain this? I thought you showed the mirror image of the achiral molecule at 9:05.
The achiral molecule at 9:05 had mirror images that were superimposable on each other. In other words, it was NOT two distinct molecules whose mirror images had separate molecular identities. It was one and the same molecule.
The statement at 9:47 still rings true. Chiral molecules must be mirror images of each other, but they must also be non-superimposable. They must be two distinct molecules that are ALSO mirror images.
Thank you very much
You are welcome
Thankyou for this.
you are welcome
Thanks a lot!
You're welcome!
so perfect, thanks
Thank you! You're very welcome!
You are a lifesaver!
Happy to help!
Thank u for make this videos
you're so welcome
1.is that chiral molecule can we interchange atoms is possible?
2. is that chiral molecule can we interchange atoms is name also enantiomer ?

at 9:32 it is the plane of symmetry.🤔

Much love for you 💖😘
Keep up
Thank you so much 🤗
@@Leah4sci you're welcome.... much love for you 💗
Very important
Thanks!
Is there a case where a wedged carbon (methyl group pointing out at you) can be chiral? Because apparently they can be according to my teacher's quiz........ but how? It is attached to one carbon and three identical hydrogens?

thanks i like ur teaching
thanks!
For fischer projection to quickly assign R or S, we can keep the lowest ranking substituent on a __axis? Mam
I have a trick for this! Make sure to watch my video on Fischer Projection stereochemistry first: czcams.com/video/lf6hLBl6wxo/video.html
Thank you.
You're welcome!
Thank you so much 😍
You're welcome!
awesome way of teaching..#sukran
