You have two attempts for this assignment. Canvas will keep the highest score. 2. You should take screenshots of all the questions (and answers) after each attempt. You are only allowed to see the questions and answers ONCE (after each attempt). 3. You are only allowed to see your score ONCE after each attempt. You cannot see the answers to questions that are marked incorrectly. You can only see which questions are marked wrong. 4. This assignment may contain some embedded images. If you cannot see the images. it is most likely because you are using an Apple, Mac, or iPad. Canvas is designed to be compatible with Google Chrome. Do not use Safari. If you have an Apple, Mac, or iPad, try installing Google Chrome and using that browser (not Safari). Also. try moving your mouse cursor over the "missing" images. Then, "right click" with your mouse. Then, select "View", "Download", or "Save As". Many students said that would work. 5. If the due date has already past for this assignment, you are still allowed to go ahead and do the assignment. Just know that you are allowed to be late for only TWO Homework assignments for the entire semester. So, you can submit TWO late Homework assignments without any late penalty. After TWO late homework assignments, all other late Homework assignments will receive a ZERO. The very last date to submit late Homework assignments (up to two late assignments only) is December 3, 2023 (11:59 PM). Take the Quiz Again

The aim of this experiment is to determine the time required to effect the complete conversion of the ketone, benzophenone to diphenylmethanol at room temperature. This investigation may be achieved by isolating and analyzing the reaction product after different reduction times. Infrared spectroscopy affords a convenient method of analysis; by comparing the IR spectrum of the crude reaction product at different time intervals one would expect to see the intensity of the hydroxyl absorption peak increase relative to that of the original carbonyl peak. From this you can deduce the optimum time for the reduction process at room temperature. Procedure Note the "reduction time" that the demonstrator assigns to your group. Different groups will be assigned different times, eithert = 2.5 minutes,…

The following figure shows the energy profile of a nucleophilic substitution reaction. Potential energy :ÖH H HII.C H C-1 H HO--C---I HH Reaction coordinate H -CH HO–CHITH H + 1 According to this, it is correct to affirm: O The activation energy (4G°) shows that it is thermodynamically favorable. O Represents a reaction that occurs in one step where a pentavalent chemical species is formed. O The intermediate has lower energy than any transition state. O The formation of the intermediate releases energy and is therefore thermodynamically favourable.
