WebMar 15, 2015 · Therefore, resonance structure A should be more stable than resonance structure B. Since resonance structure A is more stable than resonance structure B, 2-methylpropene will be more stable than trans-2-butene. Finally, we note that cis-2-butene is less stable that trans-2-butene for steric reasons. This allows us to place these $\ce{C_4 ... WebA strong restriction on the diffusion of propene in CHA was observed because the self-diffusion coefficient ratio of ethene to propene is larger than 18 and the diffusion activation barrier of propene is more than 20 kJ/mol in CHA. This ratio decreases with the increase of temperature in the four investigated zeolites.
