The central oxygen atom also has one lone pair of electrons.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The\u00a0<strong>central oxygen atom<\/strong>\u00a0has a formal charge of +1.<\/li>\n\n\n\n<li>The\u00a0<strong>double-bonded oxygen atom<\/strong>\u00a0has two lone pairs and a formal charge of 0.<\/li>\n\n\n\n<li>The\u00a0<strong>single-bonded oxygen atom<\/strong>\u00a0has three lone pairs and a formal charge of -1.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">It is important to note that ozone exhibits resonance. This means another valid Lewis structure exists where the double and single bonds are swapped. The actual structure is a resonance hybrid of these two forms, with both oxygen-oxygen bonds being identical in length and strength, intermediate between a single and a double bond.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Here is a representation of one of the resonance structures:Generated code<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>..        ..\n    :O=O \u2014 O:\n         |\n        ..<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">content_copydownloadUse code\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><em>(In this diagram, the central oxygen has one lone pair, the left oxygen has two lone pairs, and the right oxygen has three lone pairs)<\/em><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Explanation<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">To determine the Lewis structure and molecular geometry of ozone (O\u2083), we first follow the rules for drawing Lewis structures and then apply the Valence Shell Electron Pair Repulsion (VSEPR) theory.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">First, we calculate the total number of valence electrons. Oxygen is in Group 16 of the periodic table, so each atom has 6 valence electrons. For O\u2083, the total is 3 atoms \u00d7 6 electrons\/atom = 18 valence electrons.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">We then arrange the atoms with one oxygen in the center (O\u2013O\u2013O). After forming two single bonds, we use 4 electrons, leaving 14. Distributing these as lone pairs to the outer oxygen atoms first (6 each) uses another 12 electrons, leaving 2 for the central atom. At this point, the central oxygen only has 6 electrons (two bonds and one lone pair), failing the octet rule. To fix this, we move a lone pair from one of the outer oxygens to form a double bond with the central oxygen. This results in the structure described above, which satisfies the octet rule for all atoms and leads to resonance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To find the molecular geometry, we look at the central oxygen atom. It has three electron groups around it: one single bond, one double bond, and one lone pair. According to VSEPR theory, these three electron groups arrange themselves to be as far apart as possible, resulting in a&nbsp;<strong>trigonal planar<\/strong>&nbsp;electron geometry.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, the molecular geometry describes the arrangement of only the atoms. Since one of the three electron groups is a non-bonding lone pair, it is not included in the final shape of the molecule. With two bonding pairs and one lone pair (an AX\u2082E\u2081 system), the resulting shape is&nbsp;<strong>bent<\/strong>. The lone pair exerts a stronger repulsive force than the bonding pairs, compressing the O\u2013O\u2013O bond angle to be slightly less than the ideal 120\u00b0 of a perfect trigonal planar arrangement.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"1024\" src=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner5-43.jpeg\" alt=\"\" class=\"wp-image-45583\" srcset=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner5-43.jpeg 1024w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner5-43-300x300.jpeg 300w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner5-43-150x150.jpeg 150w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner5-43-768x768.jpeg 768w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Draw the Lewis structure of ozone (O3) and then determine its molecular geometry.
