Show how you would accomplish the following transformation:
cis-2-heptene to trans-2-heptene

Show how you would accomplish the following transformation: cis-2-heptene to trans-2-heptene
Show the mechanisms and reaction energy diagrams for the transformation with potassium tert-butoxide leading to trans-2-heptene. Please include a drawing of the anti-periplanar transition state. Would the transition state energy for the reaction leading to cis-2-heptene be higher or lower? Please explain your hypothesis. Would the product ratio (trans-2-heptene / 2-cis-2-heptene change if you run our experiment at room temperature instead of reflux temperature? Please explain your hypothesis.

How might you differentiate between the cis-trans and trans-trans isomers uaing spectroscopy?
You are monitoring the decay of 13-cis-retinal to all-trans-retinal. Initially, your sample contains 100% 13-cis-retinal. After 5 minutes, you see that 55% of your sample has converted to all-trans-retinal. Assume that the all-trans-retinal cannot convert back to 13-cis-retinal. a. What is the rate constant that describes the transformation of 13-cis-retinal to all-transretinal? b. How long will it take for 95% of the sample to be converted to all-trans-retinal?
