Question e and f?

7. Answer the following questions regarding this infrared spectrum. a. This compound is C5H5O. How many unsaturations are present in this compound? 2 b. What functional group represents the broad, strong peak at 3400cm1 ? c. What functional group caused the sharp, strong peak at 3303cm1 ? (Hint: it is a second functional group not associated with 3400cm1.) d. The small peak at 2120cm1 is an important peak. What functional group represents this peak? (Hint: it is related to 3303cm1.) e. Questions 7a 7d. should identify all of non-alkyl functional groups in the molecule. The peaks at 1368 and 1170cm1 yield information about this remaining alkyl group. Look in the Pretsch handout and draw the alkyl group based on these two peaks. f. Draw the structure of this compound
