If the peak is very broad and overlaps down to 2500 cm\u207b\u00b9, it is most likely a carboxylic acid.<\/li>\n\n\n\n<li><strong>Sharp Peak near 1700 cm\u207b\u00b9<\/strong> \u2013 This strong, sharp peak corresponds to the <strong>C=O stretch (carbonyl group)<\/strong>. The precise position can vary:\n<ul class=\"wp-block-list\">\n<li>Around <strong>1720 cm\u207b\u00b9<\/strong> for <strong>ketones<\/strong> and <strong>esters<\/strong><\/li>\n\n\n\n<li>Around <strong>1700 cm\u207b\u00b9<\/strong> for <strong>aldehydes<\/strong><\/li>\n\n\n\n<li>Around <strong>1710\u20131725 cm\u207b\u00b9<\/strong> for <strong>carboxylic acids<\/strong><\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Medium to weak peaks around 2850\u20133000 cm\u207b\u00b9<\/strong> \u2013 These correspond to <strong>C\u2013H stretching vibrations<\/strong>. Peaks in this region confirm the presence of <strong>alkyl (sp\u00b3 C\u2013H)<\/strong> and possibly <strong>aromatic (sp\u00b2 C\u2013H)<\/strong> groups.<\/li>\n<\/ol>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Interpretation:<\/h3>\n\n\n\n<p>The IR spectrum is a powerful tool for identifying functional groups in a molecule. In this case, the presence of a broad O\u2013H peak confirms a hydroxyl-containing group like an alcohol or carboxylic acid. The sharp peak near 1700 cm\u207b\u00b9 is a clear indication of a carbonyl (C=O), confirming that the product contains a functional group such as a ketone, aldehyde, ester, or acid. The C\u2013H stretches near 2900 cm\u207b\u00b9 are common in most organic compounds and help identify the carbon framework.<\/p>\n\n\n\n<p>By combining these peaks, we can confidently determine the presence of key functional groups and verify the identity of the synthesized compound.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-264.jpeg\" alt=\"\" class=\"wp-image-233535\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Obtain an IR spectrum of the product.
