How to determine good and bad leaving groups
WebApr 19, 2024 · 1 Answer. When a substituent leaves in a substituent reaction, it gains a negative charge. The more stable it is with that negative charge, the better of a leaving group it is. Hence, iodide and fluoride are good examples: the former is far larger than the latter, and hence more polarizable for the negative charge. WebTypically the leaving group is an anion (e.g. Cl-) or a neutral molecule (e.g. H 2 O). The better the leaving group, the more likely it is to depart. A "good" leaving group can be recognised …

WebSep 20, 2024 · Leaving group – Better leaving group leads to faster reaction rates. 1 and E1 reactions have exactly the same first step—formation of a carbocation. They differ in what happens to the carbocation. Since in both the reactions, the rate determining steps are the same, they cannot be individually controlled.
