The video tutorial explains Newman projections, focusing on drawing different conformations of a molecule by rotating around a carbon-carbon sigma bond. It discusses the stability of these conformations, emphasizing the differences between eclipsed and staggered interactions. The tutorial highlights the importance of minimizing gauche interactions to achieve the most stable conformation.
