Hooray for molecular models! Here we will examine the different conformations of ethane and butane, and discuss their relative energies. Also, Dave will show you how to draw Newman projections.

That is probably the best explanation on Newman Projections ever. I understood the subject in less than 15 minutes otherwise I'd probably spent at least 2-3 hrs to understand whats going on. Big thanks as always Prof. Dave!

Professor Dave... I pay £9000 for uni every year but what I learn from you is ten times more understandable to me than anything my lecturers teach. I just wanted to say thank you so so so much for putting all this material up for free for us because you are saving my life at the moment I LOVE YOU! KEEP UP YOUR GOOD WORK I hope you get anything you want in life you good man

I googled it when i was in 9 class because it was the weirdest unit of distance i ever heard. do you have a chart of your channel or syllabus or study map or something so that i can see whats in what videows or playlists. if not i would still make use of video labels , even though it may take some time

Your channel is just fantastic! Thank you for everything you offer to us! I have a question regarding the Newman projections. I have read that the front carbon is represented through a central dot and that the circle is representing the back carbon. Is this simply another way to interpret, to imagine, to depict the Newman projection or is one of the theories wrong?

@ProfessorDaveExplains 6 жыл бұрын

no, the circle is the front carbon! we can't see the back carbon.

No, the back carbon is obscured from view. It makes no sense to treat one carbon as a point and the other as a circle.

Well said. Should have mentioned stability between these conformations that eclipsed arrangements due to their higher energy they are unstable compared to staggered conformations (anti conformation and gauche conformation).
