Can someone help me understand these questions? Please include an explanation with the answer. Thank you!
0 1. Consider the structure of ethyl 3-methylbutanoate shown here: a. Predict 3 peaks you would expect to see in the mass spectrum of this compound. Draw the fragments which give rise to each of your peaks ã b. Predict 3 peaks you would expect to see in the IR spectrum of this compound. Include information about what causes each of your peaks. 0sC 1470cm A l Kand c. Using this re anticipate the iC NMR spectrum would look like using your carbon numbers as part of the explanation. plica of the structure, number the carbon environments then describe or draw what you held d. Using this replica of the structure, label the different hydrogens with letters, then describe or draw what you anticipate the 3H NMR spectrum would look like using your hydrogen letters as part of the explanation. Include information about not only the chemical shifts, but aso relative abundance and peak splitting as appropriate.
