Here&#8217;s the step-by-step breakdown, along with a brief explanation of the molecule\u2019s structure.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 1: Count Valence Electrons<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Sulfur (S)<\/strong> is in Group 16 of the periodic table and has 6 valence electrons. Since there are two sulfur atoms, the total contribution from sulfur is 2 \u00d7 6 = 12 electrons.<\/li>\n\n\n\n<li><strong>Oxygen (O)<\/strong> is also in Group 16, contributing 6 valence electrons.<\/li>\n\n\n\n<li>Therefore, the total number of valence electrons for S\u2082O is:<br>[<br>12 (\\text{from S}) + 6 (\\text{from O}) = 18 \\text{ valence electrons.}<br>]<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Step 2: Basic Structure<\/h3>\n\n\n\n<p>The most common bonding arrangement for S\u2082O is to connect the two sulfur atoms to each other with a single bond and bond the oxygen atom to one of the sulfur atoms. This basic structure looks like this:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>S - S - O<\/code><\/pre>\n\n\n\n<h3 class=\"wp-block-heading\">Step 3: Distribute Electrons<\/h3>\n\n\n\n<p>We start by placing single bonds between the atoms, using 2 electrons for each bond:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The two S atoms are connected by a single bond (2 electrons).<\/li>\n\n\n\n<li>The O atom is bonded to one of the sulfur atoms (2 electrons).<\/li>\n<\/ul>\n\n\n\n<p>At this point, we\u2019ve used 4 of the 18 available electrons. The remaining 14 electrons will be placed as lone pairs on the atoms.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 4: Place Lone Pairs<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Each sulfur atom has 6 remaining electrons. After forming the single bond, we place 3 lone pairs (6 electrons) on each sulfur atom.<\/li>\n\n\n\n<li>The oxygen atom, with 6 valence electrons, will have 2 lone pairs of electrons placed on it.<\/li>\n<\/ul>\n\n\n\n<p>So the preliminary structure looks like:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code> :S - S - O:<\/code><\/pre>\n\n\n\n<p>Where the &#8220;:&#8221; represents the lone pairs on sulfur and oxygen.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 5: Check for the Octet Rule<\/h3>\n\n\n\n<p>In this structure, the sulfur atoms do not obey the octet rule, as they only have 6 electrons around them, while the oxygen atom has a complete octet (8 electrons). To achieve a more stable structure, we need to create a double bond between one of the sulfur atoms and oxygen to complete the octet for sulfur.<\/p>\n\n\n\n<p>Now, if we form a double bond between one sulfur and oxygen, we shift two electrons from one sulfur atom\u2019s lone pairs to form a second bond with the oxygen atom:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>   S = S - O:<\/code><\/pre>\n\n\n\n<p>In this structure, the sulfur atoms now each have 8 electrons (forming one single bond with the other sulfur and a double bond with oxygen). The oxygen atom also has a complete octet.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 6: Resonance Structures<\/h3>\n\n\n\n<p>There is another possible resonance structure. Instead of having a double bond between one sulfur and oxygen, we could have a different sulfur atom double-bonded to oxygen. The resonance forms are:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>S = S &#8211; O<\/strong><\/li>\n\n\n\n<li><strong>S &#8211; S = O<\/strong><\/li>\n<\/ol>\n\n\n\n<p>These two resonance structures are both valid, as both sulfur atoms can participate in the double bond with oxygen, resulting in equivalent resonance contributors.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Final Structure:<\/h3>\n\n\n\n<p>The final Lewis structure for S\u2082O involves two resonance structures where each sulfur atom alternately forms a double bond with the oxygen atom. Each sulfur has a single bond to the other sulfur atom, and all atoms obey the octet rule.<\/p>\n\n\n\n<p>The final structure would look like:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>   S = S - O\n    \u2194\n   S - S = O<\/code><\/pre>\n\n\n\n<h3 class=\"wp-block-heading\">Explanation:<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>In both resonance structures, sulfur atoms share bonding electrons with the oxygen atom.<\/li>\n\n\n\n<li>The total valence electrons (18) are used up correctly, and the octet rule is satisfied for each atom.<\/li>\n\n\n\n<li>The resonance indicates that the bonding is delocalized, and the molecule&#8217;s actual structure is a hybrid of the two forms.<\/li>\n<\/ul>\n\n\n\n<p>Thus, S\u2082O exhibits resonance and follows the octet rule while minimizing formal charges.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Draw the Lewis structure for the disulfur monoxide (S2O) molecule.
