Textbook Question
Chapter 6, Problem 22E
Double bonds do not rotate freely under normal conditions. The change from Z to E requires areaction. This can occur in the presence of a catalyst or with the addition of a large amount ofenergy (e.g., at high temperature).
One such reaction is diagramed below:
(1) Add enough potential energy to break the double bond
(2) free rotation occurs at high energy transition state, then
(3) reforming the double bond as a mixture of Z and E.
Draw E-2-butene in one box and Z-2-butene in the other box, and explain your reasoning.
