What would be difference between the IRs of p-toluic acid (starting material) and 4- (bromomethyl)benzoic acid (product)? (You don’t need to look up the IR of p-toluic acid, just think about what is changing between the starting material and product). Why is IR not a good way to verify that you made product?
Homework Answers
The only difference in p-toluic acid and 4-(bromomethyl)Benzoic acid is presence of Br. This C-Br bond show stretching vibration around 500-600 cm-1. IR is not good to distinguish them because this region is not significantly important as peaks are weak and many more peaks appear in this region.

(2pt) Imagine a biochemistry lab is testing out a new procedure to improve the synthesis of a dipeptide molecule made with the amino acids Valine and Threonine. The hypothesis is that acid as a catalyst will improve the condensation reaction between the amino acids and create a greater...

“Opportunity cost” in economics basically is what you have to give up to get something—not necessarily restricted to dollar amounts. What is the opportunity cost of your going to college? (Note that this is not necessarily something that you can just look up or copy from a friend—you need to think about it and the answers may very well be different for each student. Also, I am not looking for any exact monetary calculation.) Draw a production possibilities curve for food and clothing. If...

Acid-Base Titration of a Weak Acid with a Strong Base: Determination of K. Introduction: You will be titrating a solution of a weak acid with 0.100 M NaOH, while monitoring the reaction using a pH meter. Weak acids have characteristic acid-ionization constants, K. The purpose of this lab is to use the titration to determine the value of this constant for the weak acid called “benzoic...

Jason Kemp was torn between conflicting emotions. On the one hand, things were going so well. He had just completed 6 months as the assistant financial manager in the Electronics Division of Med-Products Inc. The pay was good, he enjoyed his coworkers, and he felt that he was part of a team that was making a difference in American health care. On the other hand, his latest assignment was causing some sleepless nights. Mel Cravens, his boss, had asked him...
