- 2. The following eight structures are all isomers of C6H14O. Each structure corresponds to one of the predicted ¹H NMR spectra pictured on the next two pages of this document. The integral values for each peak are next to that peak. Indicate which structure matches each spectrum by drawing the structures in the boxes along the right side of the pages. Use the letter codes provided to label the chemically equivalent hydrogens on the structures. One example is provided.

You are calibrating a buret that is graduated to 0.1 mL. The measured volume delivered is 10.88 mL at 24.000°C. The calculated actual volume based on the mass of water is 10.859 mL. IMPORTANT: The actual volume is reported to 2 decimal places since the buret volume is reported to 1/100 of a mL. The buret error (mL) is: -0.02 0.02 -0.021 0.021
