These bonds are arranged in a trigonal planar geometry, where the bond angles are approximately 120\u00b0.

It also has one lone pair of electrons. However, this lone pair is delocalized, so we don&#8217;t count it as a separate electron domain in the traditional sense.<\/li>\n\n\n\n<li><strong>Bonding<\/strong>:<br>Each of the three C-O bonds is a combination of <strong>sigma bonds<\/strong> and <strong>pi bonds<\/strong>, with resonance occurring between the bonds, meaning that the double bond character is spread across the three bonds.<\/li>\n\n\n\n<li><strong>Geometry<\/strong>:<br>The ideal geometry for sp\u00b2 hybridized atoms is <strong>trigonal planar<\/strong>, which is exactly what we observe in CO\u2083\u00b2\u207b, with bond angles close to 120\u00b0 between the oxygen atoms.<\/li>\n\n\n\n<li><strong>Delocalization<\/strong>:<br>The resonance structures of CO\u2083\u00b2\u207b show that the electron density is spread evenly across the three C-O bonds. This delocalization of electrons further supports the idea of sp\u00b2 hybridization, where one of the orbitals overlaps with the p orbital of oxygen to form a <strong>pi bond<\/strong>, and the other two form <strong>sigma bonds<\/strong>.<\/li>\n<\/ol>\n\n\n\n<p>Therefore, the carbon atom in CO\u2083\u00b2\u207b is sp\u00b2 hybridized, reflecting its trigonal planar structure and delocalized bonding.<\/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-banner6-1113.jpeg\" alt=\"\" class=\"wp-image-261160\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>What is state of hybridisation of C in CO3^2 The Correct Answer and Explanation is: The carbon atom in the carbonate ion (CO\u2083\u00b2\u207b) is sp\u00b2 hybridized.
