Rank the following set of compounds in order of increasing leaving group abililty in an addition and elimination mechanism (poorest leaving group at the left, best leaving group to the right).
Cl- best leaving group, because its weakest conjugate base
CH3COO- ,
-OCH3
NH2-
Cl- > CH3COO- ,> -OCH3 > NH2-

Rank the following compounds in terms of increasing basicity. Enter the letters in order for example ABC if you think that is the order of increasing basicity. The most basic goes last. NH2 NH2
3. Rank these six ions/molecules in order of increasing leaving group ability (1 good, 6 poor) Remember that the weakest bases make the best leaving groups. (2.5 pts) 4. Three of the four reactions below contain a significant problem or error. Choose the letter (a statement that best describes the problem or error. write OK: Evaluate only what's written on this page: do not consider missing curved arrows, missing lone - f) of the If nothing is wrong. Do not...
