how to draw newman projections from bond line
Here is the Newman projection of a hydrocarbon. A Newman Projection focuses on one specific bond of the molecule and note which atoms are attached to these.
How To Draw Organic Compounds In Expanded Condensed And Skeletal Structural Formula Structural Formula Chemistry Organic Chemistry
A Newman projection is a representation of the molecule looking through a C-C single bond.
. Everything on the right side is assumed up configuration while all the groups on the left are down. Regardless of the molecule shown in bond-line Newman or Fischer projection it is still the same molecule. This video describes how to convert bond-line structures into Newman projections.
Find the two bonded atoms which will be at the center of the Newman projection and draw all the substituents on each atom. A Newman projection is a way to take a snapshot of what a molecule looks like at a particular moment in time from a different angle than were used to. Welcome to the first Orgo Made Easy - Chem Survival Collaboration video.
Find the longest continuous chain of carbon atoms. Find the longest continuous chain of carbon atoms. What is its bond-line notation.
How to draw a Newman Projection 1. Professor Davis of ChemSurvival Enterprises and Frank Wong of Orgo Made Easy team up to explain how to quickly convert bond-line representations into New. Draw two Newman projection templates.
It gives no stereochemical information. A bond-line view provides none. So Im going to draw this exact thing but with a Newman Projection you draw the carbon molecules directly in front.
Remember the implicit hydrogens on the carbons. On one circle draw a Y. Put a dot in the centre of each.
It tells you only which atom is connected to which. Determine which two carbon atoms are being studied. C-3 is hiding behind the circles.
For every Newman projection you need to specify the bond and the direction you are looking at. Draw a template for a newman projection. And to visualize it a little better Ill draw whats called a Newman Projection.
There is one C atom at the centre. What is its bond-line notation. It could represent any of the 16 stereoisomeric aldohexoses.
Click to see full answer. In the video below Ive distilled the process for doing this and I guide you through two examples. Grab my free eb.
And therefore it must have the same absolute configuration of all the. Find the side view you are going to be using. Newman projections focus on any.
Once youve mastered the art of naming alkanes sooner or later in organic chemistry youre going to have to draw Newman projections. Here is the Newman projection of a hydrocarbon. Put a dashed line straight down from top to bottom the middle of the projection.
Newman projection to bond line notation trick leah4sci. And not just draw them but convert between them and line-bond aka bond-line or zig-zag structures. Newman Projection to Bond-Line Notation Trick - No model kit requiredStruggling with Orgo.
From peoplebethelksedu Step 1. Davis of Georgetown University and I have worked on this and another video for. When looking at the alkane you want to decide which bond you will be looking at and from.
