Hydro cracking: It is a catalytic cracking process, where it uses hydro cracking … WebCracking Reactions. Cracking, or beta-scission, is a key feature of ionic cracking. Beta-scission is the splitting of the C-C bond two carbons away from the positive-charge carbon atom. Beta-scission is preferred because the energy required to break this bond is lower than that needed to break the adjacent C-C bond, the alpha bond.
