WebCristina BUTA, Scientific Researcher Cited by 74 Read 12 publications Contact Cristina BUTA WebComparing Equation 10.6.12 with Equation 10.6.12, the total π energy of butadiene lies lower than the total π energy of two double bonds by 0.48β (the σ bond does not contribute). This difference is known as the delocalization energy; a typical estimate of β is around -75 kJ/mol, which results in a delocalization energy for butadiene of ...
