      The capitalization of education where it’s no longer about learning but about convincing your future overlord that you are a good enough tool to be used and maybe if your lucky he will then award you a livable wage.

    Well after a very quick simulation, it came out that the difference between staggered and eclipsed was ~12kj/mol -> this corresponds to the termal energy at about 1.5K, so ethane freely rotates at essentially all temperatures. As for the usefulness of Newman projections, outside of stereochemistry, newman projections can be useful to justify major and minor products, especially in elimination reactions!

    I think one thing I haven't heard Sal say (yet at least) which is a very useful idea is this: The atoms 'try' to pack in space in a way that will make each one as FAR away as possible from the others.

    For the people asking, this can be done via "paint" program....
    just fill the background with black, and do it. or do it on a white background

    Great video!!!...the color scheme helps a lot here...one note though...the terms Configuration and Conformation are different especially in organic chem. Configuration refers more to the stereochemical aspect of molecules where bonds must be broken but in conformations, only rotations around a sigma bond occur. It's kinda annoying but many professors accentuate this distinction.
    Thanks again!

    How do u know which is the correct way the substituent belong. It could be on either side and called the same thing. Due to that, there's uncertainty where it goes on a Newman project. Which is the correct way?

  • @yosanw
    @yosanw 12 ปีที่แล้ว

    just to make sure: i thought i there was a higher potential energy when the electrons were further away from the nucleus? meaning staggered will have a higher potential energy.
