THANK YOU SO MUCH! YOU ARE A BLESSING, SIR! I'm taking the MCAT soon and I struggled with this topic and now I finally understand after graduating uni😭💖
Great to hear! Stereochemistry in general is a hard topic for many students. I've got more tutorials on most common topics, so check out my other stuff and if you have questions, feel free to ask!
Thank you so much for your work , this whole semester has been difficult understanding but with the imaginary line and adjusting the compound to make it for a more straight view helped me alot , thank you!
I'm so glad to hear that my video was able to help you out! It's always rewarding to know that my content is making a difference. Keep up the great work and don't hesitate to reach out if you have any more questions!
Hello, I have questions when adding hydrogens. I'm unsure where to place them or if they will be dashed or wedged. For example, I am not sure if I should place them on top or bottom or if that bond should be dashes or wedged. Any tips or videos you can direct me for this?
That's 'coz nobody explained to you how to properly read/write the dash-wedge structures 🙃 I have the appropriate info spread out in a few videos on Lewis structures and I have it in a few places on my website as well, but the question keeps popping up, so I think it's my queue to make a dedicated video about it.
At this point the only suggestion I have for you is to sit down with your instructor or an *in-person* tutor and go through the steps one-by-one with the molecular model kit at hand. 3D is a very important part of organic chemistry, so you will have to build up this skill.
I dont understand in which compound e hve to rotaate to see the horizon and why you didnt draw eclipse in 2nd praftise example even here we have u shape pls help
The u shape only matters when its ends are made by a bond in the same plane. In the first example, he draws it eclipsed because the wedge bonds make the “ends” of the U shape. However, in the 2nd example, the U shape is made by a wedge bond and a straight line bond.
It's on the wedge, so it's coming out of paper, right? Now, put a pencil on a piece of paper standing up towards you and hold it in this position. Then, put your head on the desk looking at it from the left (your left ear should be pressed agains the desk). From that perspective, would the pencil be pointing to the right or to the left?
@@VictortheOrganicChemistryTutor ty for the help. side question if I was looking through the c-c bond from the left direction instead would that HO group then be on the left side or no?
My test is tmr please answer how do I know which has the wedge vs which one has the dash just from the bond line drawing my teacher just puts one wedge in the center and then nothing else
I’ve answered this in the comments before. Also, I have more tutorials on the matter on my site, you might wanna check it out. And, of course, don’t put studying off till the very last day in the future 😉 Best of luck on the test! 🤞
I have another tutorial where I talk about the bond-line structures and how to deal with dashes and wedges properly, also have more on that on my site. At this point if you’re doing Newman projections it’s assumed that you already know that, so your instructor won’t spend time on that. Every bit of organic builds on the previous material, so you can’t skip anything 😉
@@VictortheOrganicChemistryTutor Sir I am pursuing B pharm in India but l love so much Organic chemistry (chemistry)... All Your Reaction I try to solve from X site...
On the second example shouldn’t the OH and the ethyl group swap places on the front carbon since the ethyl has the wedge and the OH has a dash from the perspective you are looking at 6:45
But what makes it confusing is that when I look at it it looks like the ethyl group is from the right from the way Im looking at it and even with the dash, it looks like it is going on the left
@@ryantran4306 That's why I give a set of shortcuts at around 3:00 mark b/c visualizing the molecules w/o a molecular model kit is pretty tough. So, you might wanna invest into a kit and see for yourself how the molecule would look like once you build it. I do think I need to make a video where I explain it with the model kit as these questions keep coming.
i think you need to explain it as if you're speaking to a baby It's my first time learning these for my self-learning ochem class and I didn't even know the reason why the first triangle in the projection was upright or not. I STILL DONT KNOW IN FACT. Also for the examples... I NEED MORE THAN JUST THE ANSWER... sorry if icame off rude but it's a pain watching all these videos and still not having a clue what im doing
Hey there! First off, no worries about coming off as rude. Learning organic chemistry can be like trying to tame a wild beast, so frustration is absolutely understandable! 😅 Organic chemistry is definitely not an "intro to college 101" course. It's more like the "how to perform a tricky balancing act while juggling flaming torches" level of academia. So, you're expected to have a grip on some foundational concepts, like 3D structures and VSEPR theory, before diving in. These topics are covered in general chemistry, which is pretty much always a prerequisite for organic chemistry. In the video, I designed a step-by-step guide that's basically a foolproof "recipe" for solving the problem. If you follow those steps to a T, you'll get to the right answer. 😄 This approach does, however, assumes you have at least some rudimentary 3D skills. If you're still lost, it might be a sign that you need more personalized help. Consider working with a tutor to tackle your specific challenges step-by-step. There's only as much a video can do. Do you know how to build a molecule with your molecular model kit? Do you have a molecular model kit to begin with? Start from there. Once you can build a model, then rotate it in space to literally see what the Newman projection represents. Organic chemistry assumes **prior knowledge**, so if you're struggling with the basics, you might need to back up a bit and tackle those first. The guide in my video is a tool that will work if used correctly. If it's not clicking, consider getting extra help from a tutor. And hey, we've all been there, so hang in there! 👍
Sir, in the example 2 methyl which is attached to the first carbon is having a solid line so we have placed it on the vertical line but the hydroxyl group is pointing away from us and vinyl group is pointing towards us , so we have to show hydroxyl group on the left side( dashed bonds on the left side) and a vinyl group on the right side( wedged bonds on the right side ) . I have read about this in the books as well as heard in many TH-cam tutorials for example organic chemistry tutor. Thank you so much Sir, for you kind response. Love you❤
I'm not going to comment on the quality of other's videos or books. Rewatch my video again. Pay attention to what I say at 03:00 point. AND BUILD THE MOLECULAR MODEL if you (evidently) can't visualize the molecule! I have more videos on the Newman projections. Watch those too. What you're describing ONLY works if we look at the molecule from the left. If you're going to rely on the trick and you don't understand how to even use the trick properly to begin with, you're just guessing at that point. In example 2, we're looking at the molecule from the right! So, all of your directions are now reversed! The position of the group in the Newman projection depends on the direction of how we observe the molecule, not simply if it's on the dash or a wedge.
Well, I am not going to comment on how others teach it, but I can guarantee if you follow my steps to the letter. you'll always get the correct Newman projection.

I struggled a lot with envisioning newman projections but your highlighted horizon line helped me so much thank you!
3D is a challenge for a lot of students. I’m glad my trick helped you visualize the molecules!
awesome way to explain, most professors struggle to explain these concepts
This was so helpful! thank you so much for clarifying the Newman projection rules!
byeee, you slayed this explanation. i finally understand how i'm supposed to be looking at these structures
THANK YOU SO MUCH! YOU ARE A BLESSING, SIR! I'm taking the MCAT soon and I struggled with this topic and now I finally understand after graduating uni😭💖
Best of luck! I'm glad my tutorial helped you 😃
Finally made this really clear for me! My thousand dollar courses couldn’t teach me this well!

this was so helpful thank you:)
I’ve also just uploaded video with a bunch of Newman practice questions where I quickly solve them using this approach.
Best Video ever on this topic!! Easy Points on the exam now!!!
🙌 that’s my goal 🙌

You are so welcome!
It was a great video thank you!
Thank you sir
This was super helpful and well explained. Thank you!
You’re very welcome! I’m amazed that neither instructors nor textbooks ever cover this method 🤷♂️
this was so helpful man thank you so much!!
Glad it helped!
Thank you so much for your videos! it makes me like a bit more chemistry haha
Haha, I'm glad I can make chemistry a little more bearable for you! Who knew it could be fun?

How did you do
Amazing Amazing Amazing 🤯

Thx that was helpful

question: for example #1 at 5:36, why does the HO group go to the right of the Newman projection and not the left?
It's on the wedge, so it's coming out of paper, right? Now, put a pencil on a piece of paper standing up towards you and hold it in this position. Then, put your head on the desk looking at it from the left (your left ear should be pressed agains the desk). From that perspective, would the pencil be pointing to the right or to the left?

Hi sir 🙏🙏🇮🇳🇮🇳...(India).
Sir please make the videos on wages desh projection to Fisher projection..
That’s not a bad idea. I’ll add it to my to-do list.
@@VictortheOrganicChemistryTutor Sir I am pursuing B pharm in India but l love so much Organic chemistry (chemistry)... All Your Reaction I try to solve from X site...
how do I convert bond line structures into dashes and wedges?
For questions like this, stereochemistry should be given to you. If not, you can assign dashes and wedges arbitrarily.
Tq bro
On the second example shouldn’t the OH and the ethyl group swap places on the front carbon since the ethyl has the wedge and the OH has a dash from the perspective you are looking at 6:45
It’s on the dash, which is behind the plane of paper, which is on the right from that perspective.
But what makes it confusing is that when I look at it it looks like the ethyl group is from the right from the way Im looking at it and even with the dash, it looks like it is going on the left

I think you have drawn the wrong newman projection of example 2
Nope, I didn’t. Maybe you can build a molecular model and look at the molecule from that side of it is hard to visualize.
