Reactive collisions between alkali ions (Li{sup +}, Na{sup +}, and K{sup +}) and halogenated hydrocarbon molecules have been studied recently in our research group. In this paper, we have reported on the K{sup +}+i-C{sub 3}H{sub 7}Cl system in the 0.20-14.00 eV center-of-mass energy range using a radio frequency guided-ion beam apparatus developed in our laboratory. Aiming at increasing our knowledge about this kind of reactions, we compare our latest results for K{sup +} with those obtained previously for Li{sup +} and Na{sup +}. While the reaction channels are the same in all three cases, their energy profiles, reactivity, measured reactive cross-section energy dependences, and even their reaction mechanisms, differ widely. By comparing experimentally measured reactive cross-sections as a function of the collision energy with the ab initio calculations for the different potential energy surfaces, a qualitative interpretation of the dynamics of the three reactive systems is presented in the present work.
