A. Build the ethane molecule. Rotate the molecule around the C-C bond to view the staggered and eclipsed conformers. Draw the sawhorse projection and the Newman projection in the table below. Sawhorse Newman Staggered Conformation Eclipsed Conformation B. Build the butane molecule (CH3CH2CH2CH3). Sighting down the C2-C3 bond, draw the Newman projections of the four conformers that correspond to the local maxima and minima in the energy diagram (i.e. gauche, anti, etc.). Draw the energy diagram and calculate the energy differences. The Y-axis is energy and the X-axis is degrees of rotation, which represents the dihedral angle between C1, C2 and C3. When rotating, keep C2 stationery, and rotate C3

Organic molecules are 3-dimensional, although it is sometimes easy to forget this when we see them in 2 dimensions on a sheet of paper or a blackboard. The purpose of this experiment is to familiarize you with the 3-dimensional structure of molecules, and to familiarize you with manipulating those structures. We will do this using a molecular modeling kit. A. Build the ethane molecule. Rotate the molecule around the C-C bond to view the staggered and eclipsed conformers.
