Concept introduction:
Conjugated dienes are defined as two double bonds separated by one single bond. They are more stable than non-conjugated double bonds due to resonance and hybridization energy. Along with that the heat of hydrogenation effects the stability of conjugated dienes. It states that higher the heat of hydrogenation energy lowers the stability of dienes.
