If Newman projections and conformational analysis feel tricky, this tutorial shows you exactly how to convert any line‑angle drawing into the correct Newman view - from the left and the right - and then tackle staggered vs. eclipsed examples. You’ll learn a simple 3‑question method to place groups correctly (front/back carbon, northern/southern hemisphere, vertical/left/right) and avoid the classic mistakes that cost points on quizzes and exams.
What you’ll practice:
• Reading line‑angle structures from multiple perspectives
• Building accurate Newman templates (dot + disc)
• Placing substituents with 120° offsets (staggered) or fully aligned (eclipsed)
• Quick checks that catch front/back mix‑ups before they happen
