Electrophilic addition reaction of conjugated dienes that occur at high temperature and/or long reaction times (reversible conditions) are said to be under:
A)1,2-control
B)kinetic control
C)1,4-control
D)thermodynamic control

Question

Quizplus · Accepted Answer

When electrophilic addition reactions of conjugated dienes occur under high temperature and/or long reaction times (reversible conditions), they are said to be under thermodynamic control. This means that the reaction will favor the most stable product (usually the one with the most substituted double bond) rather than the one formed kinetically (usually the one with the least substituted double bond), which would be favored under kinetic control. Therefore, the best choice is D, thermodynamic control.
