Would you expect the dipeptide valylalanine to give a positive reaction with nitric acid solution? Why or why not?
Homework Answers
3)
The answer would be" No" because a positive reaction (giving yellow color) with nitric acid would only given by tyrosine and phenylalanine and your amino acid ie valylalanine doesn't contain either of these amino acid.

What is Zaitsev’s rule? Give the mechanism for the acid-catalyzed E1 reaction of 2-butanol. Give the mechanism for the base-catalyzed E2 reaction of 2-bromobutane. Draw all possible products. You expect three products from the elimination reaction 2-butanol. What are they? The E2 mechanism is a one-step mechanism. True or False? Explain. Which of these two alcohols would you expect to be more reactive under H3PO4/aqueous conditions? Why? Give the structure of the main product in both cases. 1-phenyl-1-propanol 1 -cyclohexyl-1-propanol...
