Choose all that apply I. NH2- ia a good leaving group because it reacts readily with water. II. Stable anions are the best leaving groups, but are only important in SN2 reactions III. Stable anions are the best leaving groups and are important in both SN1 and SN2 reactions as the leaving group develops a partial negative charge in the transition state of both mechanisms. IV. Iodide anion is the best leaving group followed by bromide anion and chloride anion...
