3D Structure and Bonding: Crash Course Organic Chemistry #4
The organic molecules that make up life on Earth are more than just the 2-D structures we’ve been drawing so far. Molecules have 3-D shapes that help us understand what they can do. In this episode of Crash Course Organic Chemistry, we’ll learn how orbital hybridization and valence bond theory can help us explain 3D molecular structures and about constitutional and geometric isomers.

I just want to say Deboki is such a wonderful teacher! As awesome as the marvelous Hank. Crash Course has been a lifesaver during lockdown--keeping me smiling and learning.
The only class that's fun to listen to. Your work is amazing and you inspired me to start my own channel!
I'm so glad I rewatched Crash Course Chemistry during the time between Organic Chemistry #3 and this one.
The D orbitals: "I don't feel so good".
I love this!! I have a passion for sharing educational content in creative ways too. Love that the crash course team opened up to organic chemistry.
Needed to review organic chem for biochem and this is so helpful!!! All the memories from orgo came flashing back and I'm eternally grateful to you guys! Thank you for explaining complex ideas in a simpler way. Keep up the good work and congrats on 11 mil!
"imagine you've never seen a real-life cat" i can not imagine such a terrible thing
I don’t think I’ve enjoyed a series this much since the very first biology course. Great work!!
I love this channel. The presentation is so incredibly dense, but that's OK because rewinding is easy...the visuals and explanations are so good, and the summary at the end locks in the concepts (more or less haha)
these videos are a great review of ochem! I took ochem a few years ago and its nice getting a refresher while im doing my masters in chem.
Can't wait for the next episode... Very helpful !!!
We all know we needed this
Before I don't even know a single word about organic chemistry but thanks to you so much that I am now able to understand chemistry you literally make chemistry fun for me thank you so much from the core of my heart 🥺❤️❤️
No lies I don't understand a lot about what you're talking about as I'm a linux server admin/engineer but your videos are fun to watch and sometimes I pick up things
love the visualization, keep it coming!
I feel so vindicated in the fact that Rosalind Franklin got a Thought Bubble version of herself and Watson and Crick didn’t...
More videos on Org chem plz... I literally cried learning Org chem myself since my teacher is shite at school.
Im enjoining this subject so much! Great work
Good approach with the Thought Bubble - Rosalind Franklin appears directly and is named verbally, Watson and Crick are just text names. Covers the history pretty well.

The Geometric isomer analogy was super cool! Also could Hank appear as a guest some fine day xD ?
Cool 😎 way of making geometric isomerism easy to understand. Thank you very much
I love organic chemistry 😍
thank for this series and you guys
Ty. I think now i can fall for chemistry before you! Amazing
Crash Course deserves way more Subscribers than this!
Love these vids!
Can’t wait for pushing electrons!

My new a level chemistry teacher
Free rotation also called conformations 😃👍 nice episode✔💌
So informative, hope I could do like this. 😇
Finally some credit for Rosalind before fuckn watson and crick
AmaZing!

@@160p2GHz i highly doubt that they do. General chemistry is a prerequisite to organic chemistry, and high school chem classes are way easier and not as comprehensive as general chemistry i took in college. If they do, they either dumb it down, or have a college level professor come host an ap class for people that already took ap general chem.

O-chem doesn't seem that intellectually challenging to me but the sheer amount of information is soo daunting that you just end up mindlessly cramming stuff due to lack of time and stuff..... :/
Thanks
I am going to be studying Organic Chemistry next semester and these videos really help! Does anyone know good resources for practice problems? The videos are great but I need some extra practice.
This is for revision!! If you guys want to study in detail I would recommend epic goc series by Pahul Sir on youTube... Namaste! 😊
9:12 there's a mistake in the corner, Guanine and Cytosine need to be bonded by a triple bond, not double bonds.
Can you explain more about the bonding and orbitals?
👓 Thank You!
You are hwat? A wizard, Harry.
Psst, hurry and get to mechanisms before my next organic chemistry uni course
please make a course on english grammar , syntax, rules , direct indirect etc.

*"Trying to force a square peg in to a hole"* giggidy
You can just get a square peg through a round hole by smashing the peg into the hole and just breaking the area around the hole and putting it in
ok so the way I see it is that this is just above the abstraction level of quantum theory. In other words, it’s the smallest you can go before stuff gets REALLY weird (where particles pop into and out of existence according to probability)

“I’ll just do a quick recap of VSEPR” So you did a crash course inside of another crash course? Nice
"The thinking mind must constantly be stirred by new experience and by adaptation to new experience and new understanding in order to be vital and capable of learning. It is like stirring concrete. If you do not keep stirring it and adding water and new things to it, it hardens. And once it hardens, it can only be broken. People who are learning and living The Way of Knowledge are constantly being renewed and refreshed because they are close to life, and they are close to Knowledge. Their thoughts change, grow and evolve. Their ideas change, grow and evolve. Their conclusions change, grow and evolve. They can do this because there is something greater. There is Knowledge, the dynamic force of life within you, within the world and within the Greater Community as well. Knowledge brings you to the edge of life where you have to learn and adapt, communicate and contribute. This keeps you young, alive and close to the heart of life. Your mind, then, becomes constantly relevant to the present and is able to prepare for the future." This is a quote from a book titled Living the Way of Knowledge. For those who wish to educate themselves about the human mind, about the deeper spiritual intelligence within each person, about the meaning and purpose of life, about the great changes happening in the world and even greater yet to come, about the Greater Community of intelligent life in the universe, you can read this book free online, among many others at *NewMessage org*

Hi madam good information
Is it just me that uses this channel as there new history and science teacher
6:26 7:03 7:56 till 8:26
What happened to the original crash course music in the beginning of videos
The cat example helped a lot to understand the importance of DNA, especially for all cat lovers like me😄😄
At 7:22, you said that the molecules in this course with triple bonds will have 1 sigma bond and 2 pi bonds, I thought that this was true for all triple bonds, are there triple bonds where this is not the case?
1:39 Ok it's been a few days but I'm finally back Jesus and btw neither of those videos talk about VSEPR
Make a course on/for english grammar

wonderful teaching..thank you..
"Imagine that you have never seen a cat." NO! If that's what I need to do to learn orgo, then I will take the 'F'!
What did Watson and Crick discover? Rosalind Franklin's notes.
The animators of these contents deserve a big salute but the teachers a middle finger!!!They are just telling who did this ,when he did this most of the time giving less time to the concept what we actually need.They have been working on these things for their entire life but almost all of us watching this are new to this.I understand this stuff,but not deeply ,because they just introduce unrelevant things,this topic was to be corely focused how molecules actually look at a deeper level,the animations are the only reasons to watch these videos .Einstien said,"If you cant explain the thing you know to a 6 year old,then you are actually either showing off or not getting yourelf". These people have understood no doubt for their life is just rumbling around these things and they fall into the second category of einstien's saying
Wooooo
