how to draw newman projections from chair conformation

Draw your biggest substituent on the back carbon on the up stick 3. In this case it is going to be the Y shape since there are two groups pointing up and to the sides H and Cl.

How To Draw Chair Conformations Of Cyclohexane Rings And Recognize Equivalent Representations Youtube

But unlike the axial line this one will start on the carbon and form a slight angle outward of the chair drawing.

. Join the two diagrams with the front carbon C-6 at the top and the rear carbon C-3 at the bottom. Draw side-by-side projections of the C1-C2 and C5-C4 bonds. We are talking about the front carbon shown in red.

When drawing Newman projections look at the molecule from a. Number your atoms 1 through 5 starting from. For the chair form view the diagram so that the carbon atom nearest to you C-6 is up C-2 is behind C-1 and C-4 is behind C-5.

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. H This single bond fixes all of the other bonds in the Newman projection. To draw Newman projections for the chair conformation of cyclohexane we also need to pick up the C-C bond to view along just as we did for alkanes.

Draw the equatorial substituent up or down the reverse of the axial substituent. Add the groups here they are H atoms to the bonds. Draw Newman projections of the lowest and highest energy conformations of propane.

Steps for Converting Fischer to Haworth. Pick any ONE carbon and locate its axial substituent. Stagger back groups relative to front groups.

Make sure front connects to front and back connects to back. Since there are a total of six C-C bonds we will pick two of them and these two need to be parallel to each other. Online lectures from Kahn Academy.

Divide front view into thirds. 2-3 means looking down the carbon 2 and carbon 3 bond. When looking at the alkane you want to decide which bond you will be looking at and from which side.

Find the side view you are going to be using. Draw an eclipsed Newman projection with three sticks on the back carbon and three on the front. 1 Determine if the Newman projection is going to have the Y shape or the upside-down Y shape.

Test your understanding with this Chair Conformations of Cyclohexane Quiz as part of the Cyclohexane Chair Conformation Video Tutorial Series. Now to make a cyclic hemiacetal from your linear Fischer projection youll need to follow a few simple steps. Download my free guide 10 S.

Draw a Newman projection looking down the C2-C3 bond of 1-butene in the conformation shown below C2 should be your front carbon. This will usually be indicated by an arrow showing the front carbon or the dot of your Newman projection. Add an eye with an arrow looking down the carbon-carbon bond being studied.

Draw connections over to parallel Newman projection. Newman projections focus on any two carbons and the groups coming off them in a molecule by shifting the view from which the molecule is visualized. Draw a Haworths stem like in the picture above.

How to draw a Newman Projection 1. Converting Cyclohexane Chair Conformations to Double Newman ProjectionsNeed help with Orgo. Add the other two front.

Determine which two carbon atoms are being studied. How to draw a Newman projection of a cyclohexane ring. Have a stick up on both the back and front carbons.

Youll see a model kit compared to the drawing to help visualize the transition. Do NOT draw these straight in the x or y plane. Draw the skeletal structure.

This question takes a complicated substituent filled Chair Conformation and transforms it into a Newman Projection. A Newman Projection focuses on one specific bond of the molecule and note which atoms are attached to these carbon atoms. Draw your biggest substituent on the front on the up.
