Which compound would you expect to have the greater heat of hydrogenation: 1,2-pentadiene or 1,4-pentadiene?


Expert Answer

Step 1

Below is the reaction of both molecules which will happen during hydrogenation.

Chemistry homework question answer, step 1, image 1

Since the product in both cases is same. Hence the energy of product is same in both.

Now since heat of hydorgenation is =  energy of reactant - energy of product 

Hence the reactant which has less rea...
