There are two kinds of Newman projections: Staggered and Eclipsed. Staggered conformation is always more stable and lower in energy than eclipsed. When two big groups in the staggered conformation are next to one another, this is called gauche (less stable due to the groups bumping into one another). When two groups are opposite of one another .... Dentist that accept caresource for adults near me
