Question

According to YOUR EXPERIMENTAL OBSERVATIONS, which isomer of 1, 4-diphenyl-2-butene-1, 4-dione is more stable? Explain how you arrived at your answer. Which of the two definitions of stability in the "Principles" section did you use? Is your answer consistent with the findings of other chemists on the relative stabilities of cis and trans alkene isomers? Give the reference you used to obtain the needed information. What experimental observations DID YOU MAKE which support the theory that there is restricted rotation around double bonds?
