Conformational Analysis of Ethane and Butane - Newman Projections

The video tutorial introduces conformational analysis using ethane and butane as examples. It explains the concept of sigma bonds and their ability to rotate, leading to different molecular conformations. The tutorial covers how to use Newman projections to visualize these conformations and analyzes the energy differences between staggered and eclipsed conformations. It also discusses the specific conformations of butane, including anti and gauche interactions, and provides a step-by-step guide on drawing Newman projections.

What is conformational analysis and why is it important in understanding molecular structures?

Describe the structure of ethane (C2H6) and the types of bonds it contains.
