Question

Describe the following peaks by giving either the range of the absorbance in wavenumbers (for broad peaks) or the location of the centre of the absorbance (for narrower peaks). Identify what the absorbances could be based upon the regions A-F. Determine, to the best of your ability, the structure of the compound, and highlight the options from the interpretation that support your decision. The mass of the compound is 88.11 amu. 4000 3600 3200 2800 2400 2000 1800 1600 1400 1200 1000 800 600

Answer 1

Based on only the IR spectrum it's very difficult to find out the structure of unknown compound:

Here I have identified the major groups present in the compound.
