This is due to the stability of the carbocation intermediate–3° carbocations can stabilitize the excess charge much better than 1° carbocations, so the intermediate step is more likely to occur, allowing the nucleophile or base to attack during the second step … diane bird east amherst ny

"WebIn our general discussion of nucleophilic substitution reactions, we have until now been designating the leaving group simply as “X”. As you may imagine, however, the nature of the leaving group is an important consideration: if the C-X bond does not break, the new bond between the nucleophile and electrophilic carbon cannot form, regardless of whether the … " - How many steps is sn1

WebThe Royal Society of Chemistry Web6 sep. 2013 · These three types of steps are encountered in every free-radical reaction. The bottom line here is that by counting the number of radicals created or destroyed in each step, you can determine if the step is initiation, propagation, or termination. Intiation -> net formation of radicals. Propagation -> no change in the number of free radicals.
