Name_______________________________ Chem 236, Spring 2017 Chapter 15 Worksheet 4 1. How many signals would you expect to see in the 1 H NMR spectrum of each of the following compounds? Label the unique sets of protons with letters (a, b, c…). T hose protons that are chemically equivalent to each other count as one type of unique proton. 2. For the compounds in question 1, above, give the relative order of 1 H NMR signals, from high frequency (downfield, to the left) to low frequency (upfield, to the right). Use your knowledge of shifts, as well as tables in your book. Feel free to group shifts together as a general placement of the shift. (a) (b) (c) (d) (e) 3.
