Interpretation:
Energy diagram for conformational analysis of 2,2,3,3-tetramethylbutane should be sketched and also the energy difference between staggered and eclipsed conformations are needed to find out using table 4.6.
Concept introduction:
Conformational analysis is the study of energy verses different conformers. Conformers arise due to the free rotation of
Newman projection: Newman projection of molecule is one type of representations for the
The most and least energy occupied conformers are eclipsed and staggered, which are having a dihedral of ‘0’ and ‘60’ degree respectively.
If the energy levels of different eclipsed conformers or staggered conformers are same then they are called degenerated.
For eclipsed conformations, Torsional strain and steric interactions of atoms are the energizing factors.
For staggered conformations, anti-interactions and gauche interactions of atoms are the energizing factors.

To sketch and find: the energy diagram for conformational analysis of 2,2,3,3-tetramethylbutane and energy difference between staggered and eclipsed conformations.

Calculate the central, upper, and lower control limits for the c-chart and draw the chart precisely on the graph sheet provided (based on 3-sigma limits). Your chart should include a line for each of the control limits (UCL, CL, and LCL) and the points for each observation. Number the x-axis 1 through 25 and evenly space the numbering for the y-axis. Connect the points by drawing a line as well. Label each line drawn.
