Question
**Newman Projection Exercise** **Instructions:** Starting from the Newman projection below, rotate only the back carbon to provide the structure in an anti-staggered conformation. **Diagram Explanation:** The image displays a Newman projection where the front carbon has groups: CH₂CH₃ (ethyl group), H (hydrogen), and Cl (chlorine). The rear carbon has three hydrogens. The front carbon is shown as a dot with three lines representing the three bonds to its substituents. The rear carbon forms the circle with radiating lines to its substituents. **Activity:** There is a blank space with dashed borders labeled "Draw Newman Projection" where you should draw the resulting conformation once the back carbon has been rotated to achieve an anti-staggered orientation.

**Title: Understanding Newman Projections in Conformational Analysis** ### Instructions **Prompt:** Draw the conformer that would form after the back carbon of this conformer is rotated 60° to the right (clockwise). ### Diagram Explanation **Current Newman Projection:** - **Front Carbon Atom:** - Bonded to a CH₃ group (methyl group) at the top. - Two hydrogen atoms are bonded to the front carbon. - **Back Carbon Atom:** - Bonded to a bulky C(CH₃)₃ group (tert-butyl group) at the bottom. - Two hydrogen atoms are also bonded to the back carbon. ### Task To draw the new conformer after a 60° clockwise rotation of the back carbon, you would: 1. Imagine looking straight down the carbon-carbon bond. 2. Keep the front carbon stationary. 3. Rotate only the back carbon group 60° clockwise. **Diagram Area:** A dashed box labeled "Draw Newman Projection" is provided for you to practice drawing the new conformer. **Note:** This exercise helps visualize steric interactions and understand energy differences between different molecular conformations.
