As a chemist, I would need to see the actual infrared IR spectrum or have the specific absorption peaks provided to accurately identify the functional groups present in the unknown compound. However, I can provide you with a general guideline on how to interpret an IR spectrum and identify functional groups based on their characteristic absorption peaks:1. O-H stretch: Broad absorption peak around 3200-3600 cm indicates the presence of an alcohol O-H or carboxylic acid O-H functional group.2. N-H stretch: Sharp absorption peak around 3100-3500 cm indicates the presence of an amine N-H or amide N-H functional group.3. C-H stretch: Absorption peaks around 2800-3000 cm indicate the presence of alkane C-H functional groups, while peaks around 3000-3100 cm indicate the presence of alkene C-H or aromatic C-H functional groups.4. C=O stretch: Strong absorption peak around 1650-1750 cm indicates the presence of a carbonyl group, which can be found in aldehydes, ketones, carboxylic acids, esters, or amides.5. C=C stretch: Absorption peak around 1600-1680 cm indicates the presence of an alkene C=C functional group or an aromatic ring.6. CC or CN stretch: Absorption peaks around 2100-2260 cm indicate the presence of an alkyne CC or nitrile CN functional group.7. C-O stretch: Absorption peaks around 1000-1300 cm indicate the presence of an ether C-O , ester C-O , or carboxylic acid C-O functional group.Please provide the specific absorption peaks or the actual IR spectrum for a more accurate identification of the functional groups present in the unknown compound.
