# How do you go from a line structure to a Newman projection?

## How do you go from a line structure to a Newman projection?

Draw two Newman projection templates.

1. Draw two circles.
2. Put a dot in the centre of each. These represent C-2.
3. On one circle, draw a Y with the spokes radiating from the dot at 120° angles. On the other circle, draw an inverted Y.
4. Draw lines coming off each circle that bisect the angles of the Y.

Can you flip Newman projections?

These two Newman projections represent the same compound which we can confirm by flipping one of them 180o through an axis: Notice also, that the template pattern for the two Newman Projections is different. In the first one, the front carbon, has the “Y” shape, while in the second one, it is an upside-down “Y”.

### How do you convert to Fischer projections?

Fischer Projection

1. Step 1: Hold the molecule so that.
2. Step 2: Push the two bonds coming out of the plane of the paper onto the plane of the paper.
3. Step 3: Pull the two bonds going into the plane of the paper onto the plane of the paper.
4. Step 4: Omit the chiral atom symbol for convenience.

Which Newman projection has the lowest energy?

anti conformation
When the two largest groups are directly opposite to each other, we call it an anti conformation. This is the most stable conformation, thus it has the lowest energy.

## How do you know which Newman projection has the lowest energy?

When the two largest groups are directly opposite to each other, we call it an anti conformation. This is the most stable conformation, thus it has the lowest energy.

How do you tell if a Newman projection is staggered or eclipsed?

When looking at a Newman projection, the dihedral angle is defined as the angle made between two designated atoms on the front and back carbons. Staggered and eclipsed refer the relative orientation of all the bonds on the front carbon versus all the bonds on the back carbon.

### How do you convert Fischer projections?

To convert this stereoformula into a Fischer projection use the following procedure:

1. Step 1: Hold the molecule so that.
2. Step 2: Push the two bonds coming out of the plane of the paper onto the plane of the paper.
3. Step 3: Pull the two bonds going into the plane of the paper onto the plane of the paper.

How do you draw a Newman projection?

Draw an eclipsed Newman projection, with three sticks on the “back” carbon and three on the “front”. Have a stick up on both the back and front carbons. 2. Draw your biggest substituent on the back carbon on the “up” stick 3.

## How to convert Newman projection to bond-line structure?

On the back carbon, we have Br on the left, and H on the right: In order to convert a Newman projection to the corresponding bond-line structure, you need to look at it from the side. So, first, decide the direction you are going to use. It can be any – right or left unless specified in the question.

What is Newman projection in chemistry?

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.

### Is This eclipsed conformation a Newman projection?

So this is the eclipsed conformation as a Newman Projection. And as you can see, it’s eclipsed. The back hydrogens are eclipsed by the front ones. If I were to draw it perfectly, they would be right behind it.
