NMR Problem Set
Directions: Students may work together, but each will be responsible for this material for the rest
of the semester, so make sure to ask questions to help you understand, rather than just copying
answers down!
Part 1.
Determine how many different types of hydrogens (non-magnetically equivalent) are present in each compound.
Each question is worth 2 pt. (No partial credit)

Part 2.
Complete the table using the compound shown and the correlation table provided. Label each type of hydrogen
then fill in the corresponding information. Chemical shift may be a single value or a range. Let type A be the
hydrogen in the “12 o’clock” position, and then move clockwise around the compound. This question is worth
10 pts.

Part 3.
For the following compounds, draw the expected NMR spectrum. Label which peaks correspond to each type of
hydrogen (label from left to right) in the compound and include the integration value and splitting for each
peak. Each question is worth 10 points.

Part 4.
Determine the structure of the compound consistent with the NMR spectrum and molecular formula. Each
question is worth 10 points. Partial credit will be given.
