How would you expect the amino acids glycine, alanine, and phenylalanine to travel relative to each other on the silica plates using a mixture of chloroform/methanol/ammonia? Explain your answer.
Based on their available oxidation states, rank the following metals on their ability to catalyze this and other oxidation-reduction reactions. Rank from best to worst catalyst. To rank items as equivalent, overlap them.vanadium , titanium , manga..
For the following dehydrohalogenation (E2) reaction, draw the Zaitsev product(s) resulting from elimination involving C2-C3 (i.e., the carbon atoms depicted with stereobonds). Show the product stereochemistry clearly
The pKa of acetic acid is 4.76. Next, compute the pH of the same solution to which 3.5 ml of 6.05 M HCL has as well been added. Ignore the volume of the added HCL in your computation since its quantity is trivial. Utilize the Henderson-Hasselbalch..
