P chem question

[brzozowskir2]

we need to know the isomerization enthalpy for cis/trans butadiene for a p chem lab report. can anyone tell us where we can possibly find this?? help is appreciated. thanks

remember that hess's law states that any process that occurs in steps, even if the steps are hypothetical, has the same enthalpy as the non stepwise process.

 

can you draw an enthalpy level diagram which connects up the cis and the trans isomers through a known route that you CAN look up?

thanks. we ended up finding it in an OLD orgo book.
