Answer to Question #266551 in Physical Chemistry for Sona

Question

With example explain the energy calculation for butadiene

Answer 1

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 -35 kJ/mol. The delocalization energy is the extra stabilization resulting from the electrons extending over the whole molecule.
