Chem 261 1nd Edition Lecture 10 Outline of Last Lecture II. InteractionsIII. NomenclatureOutline of Current Lecture IV. Newman ProjectionV. InteractionsVI. Bonding GeometryCurrent LectureA Newman projection, useful in alkane stereochemistry, visualizes chemical conformations of a carbon-carbon chemical bond from front to back, with the front carbon represented by a dot and the back carbon as a circle (Wikipedia)The first image represents eclipsed forms, where the hydrogens are parallel. This is unfavorableThe second image represents staggered conformation, this is favorable because the bonds are as far away from each other as possible.The cost of a single H-H eclipsing interaction is 1 kcal/mol so it is not a significant difference but needs to be discussed. These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.Angle strain occurs when the geometry of the molecule prevents the orbital from overlapping atits best
