For each of the given pairs of compounds, the compound liberating most heat upon hydrogenations should be identified. Concept introduction: The heat liberation in a reaction is depends upon the stability of the reactant compounds. If the reactant compound is more stable, then the heat liberation will be less. Based on the proximity of C = C bonds in dienes, they are classified into three. Cumulated dienes: the C = C bonds are located adjacent carbons. Conjugated dienes: the C = C bonds or C = C and C = O are separated by one σ-bond. Isolated dienes: the C = C bonds are separated by two or more σ-bonds. The conjugated dienes are more stable as compare to isolated dienes because the delocalization of π bonds is taking place, so this forms some stabilization energy in conjugated system. To identify: the compound liberating most heat upon hydrogenations from the given pairs of compounds.
