Practice Organic chem Midterm 1
This exam is designed to give you a small glimpse as to the format of the exams I write. The content of the exam has no direct correlation to the difficulty of the actual exam you will take. Use this exam as another problem set so you can get a little more practice in where multiple chapters are combined into one document. It would greatly benefit you to try doing this exam first.That way, you will et a better idea as to how well you may be prepared for an actual CHM2510 exam. )
For each set of molecules below, circle the one that would undergo a solvolysis reaction more rapidly. 2) 2,2′-azobis(2-methylpropionitrile) (AIBN) is a radical initiator that results in the formation of alkyl radicals that are then able to undergo propagation. Use arrows to point out the two bonds that are most likely to break in a radical initiation sequence. 3) Each of the following reactions will not proceed as written. Use no more than ifteen (15) words per response to explain why the reactions would fail under the given conditions. ) THF is readily soluble in water while a similar solvent molecule, diethyl ether, is completely insoluble in water. What major intermolecular force is responsible for such a solubility property? Why is this force more likely to participate with THF than with diethyl ether? 5) Predict the products for the following reactions. If more than one product can be made be sure to draw all of them. For problems labeled with ‘major’ and ‘minor’ eaction products, be sure to draw the appropriate product(s) above the major/minor label.
Inorganic byproducts and mechanisms are not required to be shown. 3 2 4 6) Provide the reagents for the following transformations. Be aware that more that more than one synthetic step may be required and there may be more than one route to synthesize each product. 7) Provide the mechanism for the following transformation. Be sure to include all intermediates, formal charges and arrows that depict electron movement. 8) Provide the mechanism for the following transformation.
