Name_______________________________ Chem 236, Spring 2017 Chapter 15 Worksheet 4 1.How many signals would you expect to see in the 1H NMR spectrum of each of the followingcompounds? Label the unique sets of protons with letters (a, b, c…). Those protons that arechemically equivalent to each other count as one type of unique proton.2.For the compounds in question 1, above, give the relative order of 1H NMR signals, fromhigh frequency (downfield, to the left) to low frequency (upfield, to the right). Use yourknowledge of shifts, as well as tables in your book. Feel free to group shifts together as ageneral placement of the shift.(a) (b) (c) (d) (e) 3.Label the unique protons (with letters) and then list the splitting pattern (multiplicity) of eachfor the following molecules.
