If the 1,3-diaxial strain for an ethyl group is 4.0 kJ/mol, what is the energy difference between the axial and equatorial conformations of ethylcyclohexane?

Question

Quizplus · Accepted Answer

The energy difference between the axial and equatorial conformations of ethylcyclohexane is determined by the 1,3-diaxial strain of the ethyl group. The axial conformation experiences more 1,3-diaxial strain than the equatorial conformation, which results in a higher energy. The energy difference between the two conformations is twice the energy of the 1,3-diaxial strain of the ethyl group, which is 8.0 kJ/mol. Therefore, the answer is C.
