To determine its correct Lewis structure, we follow a step-by-step approach using the rules of chemical bonding and valence electrons.<\/p>\n\n\n\n<p><strong>Step 1: Count total valence electrons.<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Hydrogen has 1 valence electron.<\/li>\n\n\n\n<li>Carbon has 4 valence electrons.<\/li>\n\n\n\n<li>Nitrogen has 5 valence electrons.<\/li>\n<\/ul>\n\n\n\n<p>Total = 1 + 4 + 5 = <strong>10 valence electrons<\/strong><\/p>\n\n\n\n<p><strong>Step 2: Determine the central atom.<\/strong><\/p>\n\n\n\n<p>Carbon is less electronegative than nitrogen and can form multiple bonds. So, carbon will be in the center, with hydrogen on one side and nitrogen on the other.<\/p>\n\n\n\n<p>Basic skeleton: <strong>H \u2013 C \u2013 N<\/strong><\/p>\n\n\n\n<p><strong>Step 3: Form bonds and satisfy octets.<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Start by placing single bonds between atoms: H\u2013C\u2013N uses up 2 bonds or 4 electrons.<\/li>\n\n\n\n<li>Remaining electrons: 10 \u2013 4 = 6 electrons<\/li>\n<\/ul>\n\n\n\n<p>To satisfy the octet rule, nitrogen needs 8 electrons, and carbon also needs 8. Hydrogen only needs 2, and it already has them from the single bond with carbon.<\/p>\n\n\n\n<p>To complete the octets, we add multiple bonds between C and N. A triple bond between C and N satisfies the octet rule:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Carbon: 2 electrons from H\u2013C and 6 from C\u2261N = 8 total<\/li>\n\n\n\n<li>Nitrogen: 6 electrons from C\u2261N and 2 lone electrons = 8 total<\/li>\n<\/ul>\n\n\n\n<p>The final structure: <strong>H\u2013C\u2261N:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Hydrogen has one bond (2 electrons) \u2014 complete<\/li>\n\n\n\n<li>Carbon has 4 bonds (8 electrons) \u2014 complete<\/li>\n\n\n\n<li>Nitrogen has 3 bonds and 1 lone pair (8 electrons) \u2014 complete<\/li>\n<\/ul>\n\n\n\n<p>This arrangement uses all 10 electrons correctly and satisfies the octet rule for all atoms (except hydrogen, which follows the duet rule).<\/p>\n\n\n\n<p><strong>Therefore, the correct Lewis dot structure is H:C\u2261N:<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"722\" height=\"1024\" src=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner10-276.jpeg\" alt=\"\" class=\"wp-image-34514\" srcset=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner10-276.jpeg 722w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner10-276-212x300.jpeg 212w\" sizes=\"auto, (max-width: 722px) 100vw, 722px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Which is the correct Lewis electron dot structure for hydrogen cyanide, HCN?
