An unknown sample was analysed using infrared spectroscopy. What is the compound?
So I am having difficulty in using the infrared data to determine the unknown compound. I keep on misinterpreting the information on the Infrared spectrum. According to the answer provided, it is ethanamide. But how? What does the strong and broad range tell you? Is it $2730-3100$ or $3200-3600$? Why can't it be $O-H$? What about the range between $1500 - 2000$, does that correspond to $C$ double bond $C$ or $C$ double bond $O$?
How can I interpret the diagram correctly? The range seems to overlap it selves?
