QUESTION:
Consider the following two conformations of 2,3-dimethylbutane. For each of these conformations, use Table 4.6 to determine the total energy cost associated with all torsional strain and steric strain. (a) CH3 CH3 CH3 H CH3 H (b) CH3 CH3 HCH3 H3C H
ANSWER:Step 1 of 2
a. For staggered conformations, we must consider gauche interactions. Here, there are three CH3-CH3 gauche interactions. Since they cost 3.8 kJ/mol each, the strain energy of this compound in this conformation is 11.4 kJ/mol.
