# Drawing Newman Projections

As we learned already, we use Newman projections to visualize the rotations of conformers. Now we will learn the steps involved to draw the perfect one.

## Introduction to Drawing Newman Projections

__Worked Example__:Draw the most energetically favorable Newman Projection for CH_{3}CH_{2}CH_{2}CH_{2}CH_{3} down the C2 – C3 bond.

1. Convert problem into bondline structure

## Step 1 to Drawing Newman Projections

2. Highlight the bond of interest

## Step 2 to Drawing Newman Projections

3. Draw an eyeball glaring down the length of the bond

## Step 3 to Drawing Newman Projections

4. Surround only the bond of interest with ALL implied hydrogens

## Step 4 to Drawing Newman Projections

5. Draw a front carbon with 3 groups in the front and a back carbon with 3 groups in the back

## Step 5 to Drawing Newman Projections

6. Determine which dihedral angle would correspond

## Step 6 to Drawing Newman Projections

Hint:This question asked for the most energetically favorable = **most stable**. Which conformation is most stable?

The right answer was **anti.** You got it. So it turns out this time we drew it correctly on the first try. But there will be other examples where we will have to rotate the Newman Projection into the correct position.

Draw the most energetic Newman Projection of CH_{3}CH(C_{6}H_{5})CH_{3}

Hint:Not all Newman Projections can form an anti, gauche and eclipsed conformation. If you have no clear large group on one side of the projection, you’ll just be stuck with projections called **staggered** (not overlapping) and **eclipsed** (overlapping).

Draw the most stable Newman Projection of CH_{3}CH_{2} CH_{2}OH through the C2 – C1 bond.
