Let's break down the **Newman Projection** shown in the image step-by-step: --- ### **Step 1: Understanding the Newman Projection** - The circle represents the **front carbon** (C1). - The lines going out from the center of the circle are the three groups attached to the front carbon. - The lines going out from the back of the circle are the three groups attached to the **rear carbon** (C2). Let's assign: - **Front (C1):** Cl, H, CH₃ (red) - **Rear (C2):** Br, H, CH₃ (blue) --- ### **Step 2: Identify Groups on Each Carbon** #### **Front Carbon (C1)** - Cl (up) - H (down right) - CH₃ (red, down left) #### **Rear Carbon (C2)** - Br (down) - H (up right) - CH₃ (blue, up left) --- ### **Step 3: Analyze Each Option** #### 1. **Red CH₃ and Blue CH₃ are on two adjacent C's** - **True**: Red CH₃ is on C1, blue CH₃ is on C2 (adjacent carbons). #### 2. **Both H's are on the same C** - **False**: One H on C1, one H on C2. #### 3. **Cl and Br are on the same C** - **False**: Cl is on C1, Br is on C2. #### 4. **Cl, H and Blue CH₃ are on the same C** - **False**: Cl and H are on C1, but blue CH₃ is on C2. #### 5. **Red CH₃ and Blue CH₃ are on the same C** - **False**: They are on different adjacent carbons. #### 6. **Cl, H and Blue CH₃ are on adjacent C's** - **True**: Cl and H are on C1, blue CH₃ is on C2. #### 7. **Blue H and Br are on the same C** - **True**: H (up right) and Br (down) are both on C2. --- ### **Step 4: Final Answers** The correct options are: - ✅ Red CH₃ and Blue CH₃ are on two adjacent C's - ✅ Cl, H and Blue CH₃ are on adjacent C's - ✅ Blue H and Br are on the same C **(Your image shows the first and last of these correctly checked, but you should also check "Cl, H and Blue CH₃ are on adjacent C's")** --- ## **Summary Table** | Option | Correct? | Explanation | |--------|----------|-------------| | Red CH₃ and Blue CH₃ are on two adjacent C's | ✅ | They are on C1 and C2 | | Both the H's are on the same C | ❌ | H's are on different C's | | Cl and Br are on the same C | ❌ | Cl is on C1, Br on C2 | | Cl, H and Blue CH₃ are on the same C | ❌ | Blue CH₃ is not on same C as Cl and H | | Red CH₃ and Blue CH₃ are on the same C | ❌ | They are on different C's | | Cl, H and Blue CH₃ are on adjacent C's | ✅ | Cl, H (C1) and Blue CH₃ (C2) | | Blue H and Br are on the same C | ✅ | Both on C2 | --- ### **Final Selected Answers** - Red CH₃ and Blue CH₃ are on two adjacent C's - Cl, H and Blue CH₃ are on adjacent C's - Blue H and Br are on the same C Let me know if you need more explanation!
