Problem Details

cis-2-Butene isomerizes to trans-2-butene via the following reaction:

The figure shows the reaction of isomerization. The reactant is a CC double bond. Each carbon has a hydrogen atom attached below the double bond and a -CH3 group attached above the double bond. The product is a CC double bond with a hydrogen atom attached below the double bond to the first carbon and above the double bond to the second carbon. Also, it has a -CH3 group attached above the double bond to the first carbon and attached below the double bond to the second carbon.

If isomerization requires breaking the π bond, what minimum energy is required for isomerization in J/molecule?
