For Students 9th - Higher Ed. For this organic chemistry worksheet, students determine the relationships between compounds. Students use Newman Projections to draw stable conformations for compounds. This worksheet has 6 problems to solve.

by examining a Newman projection down C—C bonds on opposite sides of the ring: The staggered arrangement of all the bonds can be seen clearly in the Newman projection. This same picture is seen when the projection is viewed down any C —C bond. All the C C bonds in the molecule are in conformations in which the hydrogens are perfectly staggered.

Newman projection practice worksheet Newman projection practice worksheet with answers. Before starting our exploration of stereochemistry and chirality, first we need to consider the theme of conformational isomerism, which has to do with the rotation of individual ties.

Practice with Newman Projections for Organic Chemistry chapter newman projection worksheet draw the newman projections from the following perspective structures

Once you've mastered the art of naming alkanes, sooner or later in organic chemistry, you're going to have to draw Newman projections. And not just draw them, but convert between them and line-bond (aka bond-line or zig-zag) structures. In the video below, I've distilled the process for doing this, and I guide you through two examples.

A Newman projection is a representation of the molecule looking through a C-C single bond. For every Newman projection, you need to specify the bond and the direction you are looking at. For example, for our molecule, we can look through the C1-C2 bond (even though it can be through any bond). The direction is usually shown with an eye symbol:

So, start with the staggered Newman projection for ethane, or #"C"_2"H"_6#, which looks like this. The molecule can have no less than 2 carbon atoms, since Newman projections are made by looking down a bond of carbon atoms.These two carbon atoms that form the bond are drawn as the intersection of the three black lines - this is the front carbon atom - and as the large black circle - this is ...
