To determine the functional groups present in an unknown compound X based on its infrared IR spectrum, I would need to see the actual spectrum or have the significant peak values provided. However, I can give you a general idea of what to look for in an IR spectrum to identify common functional groups.1. O-H stretch: A broad peak around 3200-3600 cm indicates the presence of an alcohol O-H or carboxylic acid O-H group.2. N-H stretch: A sharp peak around 3300-3500 cm indicates the presence of an amine N-H or amide N-H group.3. C-H stretch: Peaks around 2800-3000 cm indicate the presence of alkane C-H groups, while peaks around 3000-3100 cm indicate the presence of alkene C-H or aromatic C-H groups.4. C=O stretch: A strong, sharp peak around 1700-1750 cm indicates the presence of a carbonyl group C=O , which can be found in aldehydes, ketones, carboxylic acids, esters, or amides.5. C=C stretch: A peak around 1600-1680 cm indicates the presence of an alkene C=C or aromatic C=C group.6. C-N stretch: A peak around 1100-1250 cm indicates the presence of an amine C-N or amide C-N group.7. C-O stretch: A peak around 1000-1300 cm indicates the presence of an ether C-O , ester C-O , or alcohol C-O group.Please provide the specific peak values or the actual IR spectrum of the unknown compound X for a more accurate analysis of the functional groups present.
