Conjugated diene addition
WebJan 28, 2024 · Conjugated dienes are known to be more stable than non-conjugated dienes as shown by their experimentally determined heats of hydrogenation. In Section 7-6, it was shown that as alkenes become more stable, they contain less energy, and therefore release less heat during hydrogenation. WebDec 24, 2015 · Conjugated dienes have enhanced stability due to resonance. So they are less reactive when compared to alkenes in general. But many reactions proceed through high-energy cation or free radical …
