1. strong base
A
2. R
Is the student's proposed synthesis likely to work?
If you said the proposed synthesis would work, enter the chemical
formula or common abbreviation for an appropriate strong base to use
in Step 1:
If you said the synthesis would work, draw the structure of an alcohol

For each spectrum, draw the structure of the compound, and assign the spectrum by labeling H's in your structure (or in a second drawing of the structure) with the chemical shifts of the corresponding signals (which can be estimated to nearest 0.1 ppm). IR information is also provided. As a reminder, a peak near 1700 cm-1 is consistent with the presence of a carbonyl (C=O), and a peak near 3300 cm-1 is consistent with the presence of an O–H. Extra information: For C6H10O2 , there must be either 2 double bonds, or 1 triple bond, or two rings to account for the unsaturation. There is no two rings for this problem.
