In CO, carbon and oxygen share a triple bond, which is a very strong and short bond. A shorter bond length corresponds to the strength of the bond. Given that CO has a triple bond, this results in a significantly shorter bond length compared to other compounds.<\/li>\n\n\n\n<li><strong>CH2O (Formaldehyde)<\/strong>: In formaldehyde, the carbon-oxygen bond is part of a double bond structure. A double bond is not as short as a triple bond but still stronger than a single bond. The C-O bond length in formaldehyde is 0.143 nm, which falls within the typical range for a C=O (double bond) bond. The bond length in formaldehyde is slightly longer than in carbon monoxide, which is consistent with its lower bond order (double bond vs. triple bond).<\/li>\n\n\n\n<li><strong>Methanol (CH3OH)<\/strong>: In methanol, the C-O bond length is 0.113 nm. Methanol has a single bond between carbon and oxygen, which is the longest among these three compounds. The single bond is weaker and longer than a double or triple bond, which explains the shorter bond length.<\/li>\n<\/ol>\n\n\n\n<h3 class=\"wp-block-heading\">Summary:<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Carbon monoxide (CO) has a triple bond (shortest C-O bond).<\/li>\n\n\n\n<li>Formaldehyde (CH2O) has a double bond (intermediate C-O bond length).<\/li>\n\n\n\n<li>Methanol (CH3OH) has a single bond (longest C-O bond).<\/li>\n<\/ul>\n\n\n\n<p>Thus, <strong>CH2O<\/strong> (formaldehyde) has the C-O bond length of 0.143 nm.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner5-872.jpeg\" alt=\"\" class=\"wp-image-246446\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Listed in no particular order, the C-O bond lengths in carbon monoxide, CH2O, and methanol are 0.121 nm, 0.143 nm, and 0.113 nm.
