Homework Answers
Good leaving groups are weak bases. The weaker the base, the better the leaving group.
Ex- Cl-, Br-,I-
So answer is V. not a strong base

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...

Which of the following statements best explains the decreased acidic nature of carbonic acid compared to other carboxylic acids? OH carboxylic acid HO OH carbonic acid A. The extra hydroxyl group on the carbonic acid is an electron donating group, dampening the acidity of the molecule. B. The carbonyl group is an electron withdrawing group, increasing acidity of the OH through resonance. C. The carboxylate anion is stabilized by hyperconjugation and is a weak base, so the conjugate acid is...
