Newman Projection Part 4 – Multi-Substituted Molecule

October 4, 2012 By Leah4sci 11 Comments

Newman Projections of Multi-substituted Molecules Organic Chemistry Tutorial VideoNewman Projection Series: Video 4
What starts out as a potentially ridiculous molecule can easily be turned into a Newman Projection if you rewrite your sawhorse or ‘sideways' structure into a 2-carbon molecule with substituents coming off it, just as they would your Newman Projection

    Would it be incorrect if I drew the entire Newman project upside down? for example the front carbon has iso-p on top H on left and methane on right and the back carbon has ethane on bottom cl on left and H on right

    Leah, I’m wondering how you know where the H will go on the molecule before even making the newman projection. Will we always be given the location (dash/wedge) of the other atoms?

    Hi Leah, I was just wondering, how do you know when to place the substituents on the right and when to place it on the left in the projection. Amazing job Btw, Thank you!

      It depends on the molecule presented. Swapping right and left will result in enantiomers so be sure to pay attention to HOW the molecule is presented.

    Thanks for the video! I have a question please, i don’t understand, is it necessary to rotate the molecule? If so how do we know when (or why) we should rotate it? (2.27-2.45)

    Hi Lea, thanks a lot for giving us so much of your time.

    i ve lost the point few videos ago. what does it change in ”real life” happening the worst conformation ? i mean when the largest groups are eclipsing each other..
