Sorry if I am miles off here, because I like your style of explanation, but ... aren't you being very casual with the word reflection? I mean ... no object IS its reflection, but it's always identical to it (in a way) or its not actually its reflection . no?
Like ... you thow a mirror in ... and you use the word reflection, but ... the mirror does the square root of fuck all in your example, so why even mention the word reflection? Am I wrong? (Probably)
You're completely right on the first point about "is" and while I agree generally about the word "reflection", I am inclined to think it is overly pedantic, because actual reflection -- e.g., light bouncing off a mirror -- is (I hope) *obviously not* what we are talking about. That doesn't answer your question about why actually use this metaphor as a pedagogical aid... I do not think most people have *really* noticed chirality as a phenomenon -- daily living does not inspire us to really articulate that some objects can be super-imposed on their mirror image and some can't. In my experience, that is the main barrier to understanding this topic (people just haven't articulated/gripped that fact enough), so the raison d'etre of the video was just to bring that concept to life. I think the use of the mirror and the pretend "reflection" does, at least for some people, succeed in doing that.
I would use "complimentary"; and "reflective" & "non-reflective". Which would also replace the negative word - describing a positive reality, and vice-versa (chiral - doesn't reflect; achiral - reflects). But education is historic - so they won't change it.
@@flydia I have no recollection of typing the original comment, but looking back at it now I have no idea what I was talking about, sorry about that chief! Thanks for taking the time to reply (which I didn't notice till now, either).
Lydia my name is Cosme Souza, a brazilian chemistry student, and I'm really grateful to have come across your vídeos. Thanks to your clarifying explanations, especially about chirality. You literaĺy saved my life. God bless you. I'll stick to your vídeos from now on.
Thanks for the video. I realized the way I was visualizing and rotating these objects didn't consider certain rotations such as the one at 1:24. Thanks so much! It felt like some of the answers and explanations I've gotten elsewhere were contradictory/incorrect. But, now it makes sense! My suffering is no more and I learned something new today!
Two compounds with same atom composition (that you showed with coloured balls) are not always each others reflection. The position where each atom is fitted matters. If the blue is on right it should be on left in the mirror image. So saying that "after rotating if its identical to original, its mirror image" is wrong. You could put a compound in a wrong orientation (hence not a reflection) but is exactly the same after being rotated 'a few times'. Conclusion : just one complete rotation (exact opposite of reflection = original)makes a mirror image. Tho you did put your compounds' reflections very mindfully to begin with (the right way)
Seriously, I never comment on videos but this is just so amazing and simple explanation which many of the teachers fail to give...good job keep it up 👍
I'm a NEET ( Indian medical entrance exam ) Aspirant And was struggling to understand mirror image rotation , spent hours searching in books for explanation But unable to find any , left it Now after nearly 8 months since I read it , my doubt is clear : )
Really good explanation. Could only be improved by focussing more on "yes it IS an accurate reflection, but NO IT'S NOT identical". Also I think there were 1 or 2 too many examples of identical objects. Thanks for your dedication in putting this together, Lydia. I now understand the concept! Beautiful accent by the way!
Great Video! One question : I am currently reading a paper about crystallography , and more specifically about the P63/mmc . From searching I found that 3 denotes the chirality. What does this actually mean ? Thank you in advance
I felt lost you when you brought purple as the last colour because I'm colour blind and can't distinguish it from blue. You were rotating it to show that they aren't identical but they look exactly the SAME to me. Good demonstration though!
Emperor Imagine if the two feet were able to pass through one another and occupy the same volume of space. The hollow openings would face in opposite directions. This factor makes them chiral. Conversely and hypothetically, if the feet where not hollow, and looked the same on both sides, then such feet would be achiral.

That is just it in a simple language! Many textbooks make it fuzzy and confusing. Glad you made it quick and simple!
Duh that's what Babel is.

You are a gifted teacher, please help us future doctors by making more videos on biochemistry! Ever grateful.
You are responsable for an "Aha!" moment, thank you!

Thanks a lot. My chem teacher sucks at explaning and he yells at us. You are a life saver!
Cheers from Portugal
It always takes a woman's touch to get the point across.. thank you : )
You have a very beautiful voice and your explanation really helped me, thank you!
Thank you so much! This is by far the easiest to understand explanation I have found.
Ann Blodgett ya true
Thanx mam.... It was very helpful.... Ka m from India 🇮🇳 ....... You are doing very well 👍keep it up...
loved the fast explanation and sped up writing so much, please continue your wonderful work.
How you doing mate ? It has been 7 years since you were here
I love how u physically esplain it. It was very clear , thank u!
Best of all the lectures about chirality because it clears achiral as well
This video is the best so far. Others are just confusing.
that was such a neatly explained video. Thanks for taking the time to post:)
Saved me a ton of time I could better spend on other MCAT subjects.

My god, I think I've finally got it! Thank you so much for using actual 3D objects to explain this.
Thanks a lot..I watched so many videos about this but I was not understanding the actual concept..you made it very clear..what an explanation
You did so good at explaining it I got it right away.
For the first time, it made sense to me. Thanks
Thank u so much I'm been searching for a long time to know what exactly chirality is . And thanks for using tetrahedral shape to explain it
This great video was shown to us in the lecture and I came here to rewatch it and thank you!
Now only I got a clear idea about this concept.thank u Soo much man
i have no words to say
i love your explanation. i was looking for it
you got a new sub
cheers
#love
Why is the second molecule chiral? At 2:34 they look like the same object.
Incredibly helpful thanks a lot!
Posso publicar seu vídeo com alterações, sem fins lucrativos, traduzindo para o Português?
Thissss is soooo gooooddd thank you soo much ….now i m very clear about chirality
Thankyou Mam!, Your video is best on RUclips which explain the concept in such a wonderful way!!
THANK YOU SO MUCH! The concept of chirality was eating up my head but you cleared my confusion completely!
I got recommended by our teacher today. I now get it why. Thanks😄
thanks for your wonderful explanation
now my concepts are crystal clear
Superb Explanation Ma'am ! 🤩
Finally The only best explication ❤️❤️
Thank you for your helping
THANK YOU for this video I was going crazy trying to understand this
Heyy, How's it going ?😂😂
I'm a NEET ( Indian medical entrance exam ) Aspirant
And was struggling to understand mirror image rotation , spent hours searching in books for explanation
But unable to find any , left it
Now after nearly 8 months since I read it , my doubt is clear : )
Super madam I am your new subscriber from India🇮🇳🇮🇳🇮🇳🇮🇳
how do you draw optical isomers? i mean, to which groups are those bold lines and dotted lines supposed to be joined??
Thanks, I understood it.Your way of teaching is awesome.
I love your explanation please continue making videos! It makes more sense now and thank you !
Very good . Wise men had said true that "simplicity is not a single thing." But simple is understandable. Keep it up 👍👌💪👍👍💪💪💪💪💪💪💪😘😘😘😘😘😘😘😘😘😘
If an object has at least one axis of symmetry, it is achiral. Is this deduction right?
thank you a lot for this detailed explanation with many examples. it was exactly right for my weak space imagination.
Do you know how the amino acid molecules of cellular proteins are left handed only and why they need to be?
Good job, u made it easy to understand it.
Holy banana... this was so simple yet so helpful!
So Did you understand it? 😂
thats good explaination toward you mam i lived in india in india is organic chemistry not done by great
awesome video. all my doubts were cleared.thank-you.
Not sure if remember it right. But isn't an orange a lemon because of chirality?
Thanks Lydia, very clear and helpful explanation :)
Can 2d molecules be chiral? Please tell me... I can't really understand how us it possible for 2d molecules to be chiral
this is just PERFECT! thank you soo much, our teacher tried so hard to explain this but wasn't successful :D
*Brilliant Understood It immediately*
Wow Lydia, a beautiful visual explanation. Much clearer than the TedEd vid on chirality. Thank you!
madam can i use your video for my channel reference ?
Really good explanation. Could only be improved by focussing more on "yes it IS an accurate reflection, but NO IT'S NOT identical". Also I think there were 1 or 2 too many examples of identical objects. Thanks for your dedication in putting this together, Lydia. I now understand the concept! Beautiful accent by the way!
Will u help me to understand some concepts
thanks for the great effort
Amazing! Thank you so much! My prof is a jerk who doesn't answer any questions and this SAVED me!
:)
this is a great explanation. Went through your channel.... Y U NO MAKE MORE VIDEOS !! ?
It was exactly what i was searching for
Thank you👍🏻
Where u buyed this ?
Fabulous 🤗🤗🤗make more👍👍
you rock ! thanks ! the best explanation over youtube !! keep on !
Great Video!
One question : I am currently reading a paper about crystallography , and more specifically about the P63/mmc . From searching I found that 3 denotes the chirality. What does this actually mean ?
Thank you in advance
Great video! You have a soothing voice!
Thank you for this! Really helped me visualize and understand the concept.
Thanks a lot! Direct and to the point.
Thank you.. you saved my life
Very nicely explained
Hi I loved this video, it really helped me a lot!!! Keep going!!!
Nice presentation.
Thankyou it gave me clarity
I wish youtube existed when I was in high school, holy shit thank you.
Hi, very lucid and nice explanation. By the way I would like to know the plastic molecular models you used, what is the name, where can one buy them.
It's a called a ball and stick model. At lease that's what they call it at my school.
I subscribed your channel with this video
what motivated you t make the video? i love it haha
That's fine... 👍
I felt lost you when you brought purple as the last colour because I'm colour blind and can't distinguish it from blue.
You were rotating it to show that they aren't identical but they look exactly the SAME to me.
Good demonstration though!
Thank you so much mam,it made me understand quickly
Omgeee Thank you for this explanation!!!! =D
had that im my medical school 1st year chemistry book, but without any example it was useless - HUDGE thanks for clearing that UP :D
2 and 5 on a seven segment display. Or s piece and z piece from tetris.
very nice explanation
Thank you so much .This was so helpful
Thank you very much! Very useful video!
this really helpful . thank you
Is this dp picture is your?
thanks ..very good method ...im from jordan
Thank you so much,it was very helpful 🙏🙏🙏
Plzz make more vidios.... Of chem...
You are the best!!!!!
❤❤ma'am you're very beautiful 😍 😍😘 but also your experience in exploring the concept
well done mam😀
Thank you ! Very clear !
Well done!
The feet were achiral.. they could be superimposed.. it was just the back was different.. but the shape tho
Emperor
Imagine if the two feet were able to pass through one another and occupy the same volume of space.
The hollow openings would face in opposite directions. This factor makes them chiral.
Conversely and hypothetically, if the feet where not hollow, and looked the same on both sides, then such feet would be achiral.
