Question
You have reacted acetic anhydride with an alcohol in the presence of a small amount of concentrated sulfuric acid in
the hope of generating butyl acetate. After isolation by extraction, you subject a small amount of the isolated material
to infra-red analysis. Which of the following may indicate a successful reaction?
A sharp peak at 1735 cm , along with other sharp peaks around 2980, 2950 and 2890 cm1
A sharp peak at 1700 cm-1, along with a broad peak between 3200 and 2650 cm1
Two sharp peaks at 1780 and 1840 cm', along with sharp peaks at 2980, 2950 and 2880 cm
A broad peak at 3600 cm, along with sharp peaks at 2980, 2950 and 2880 cm
