SiS\u2082 (Silicon disulfide):<\/strong><br>In the Lewis structure of SiS\u2082, the central silicon atom is bonded to two sulfur atoms with double bonds. Silicon has four valence electrons and each sulfur has six. Each sulfur shares two electrons with silicon to form a double bond, completing the octet for all atoms. There are no lone pairs on the central silicon atom. Since there are only two bonding regions and no lone pairs, the electron pair geometry is <strong>linear<\/strong>. This results in a <strong>linear molecular shape<\/strong> with a bond angle of <strong>180 degrees<\/strong>. The molecule is <strong>nonpolar<\/strong> because the two polar bonds are arranged symmetrically, and their dipoles cancel out.<\/p>\n\n\n\n<p><strong>2. PCl\u2085 (Phosphorus pentachloride):<\/strong><br>In PCl\u2085, phosphorus has five valence electrons and forms five single bonds with five chlorine atoms. There are no lone pairs on phosphorus. The electron pair geometry is <strong>trigonal bipyramidal<\/strong>, consisting of three atoms in the equatorial plane at <strong>120 degrees<\/strong> and two atoms in the axial positions at <strong>90 degrees<\/strong> to the equator. This gives a <strong>trigonal bipyramidal molecular shape<\/strong>. Because of the symmetry in this shape and the fact that all surrounding atoms are identical, PCl\u2085 is a <strong>nonpolar<\/strong> molecule, even though the P\u2013Cl bonds are individually polar. The symmetry causes the dipoles to cancel each other out.<\/p>\n\n\n\n<p>In conclusion, <strong>SiS\u2082<\/strong> and <strong>PCl\u2085<\/strong> are both <strong>nonpolar molecules<\/strong> with <strong>linear<\/strong> and <strong>trigonal bipyramidal<\/strong> geometries, respectively.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"852\" height=\"1024\" src=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-122.jpeg\" alt=\"\" class=\"wp-image-26859\" srcset=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-122.jpeg 852w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-122-250x300.jpeg 250w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-122-768x923.jpeg 768w\" sizes=\"auto, (max-width: 852px) 100vw, 852px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Draw Lewis structures for the following species in the boxes provided and use them to answer the questions below: What is the electron pair geometry for SiS_(2) ? a. linear b. trigonal planar c. tetrahedral d. trigonal bipyramidal e. octahedral What is the molecular shape of SiS_(2) ? a. tetrahedral b. bent c. trigonal pyramidal [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-26852","post","type-post","status-publish","format-standard","hentry","category-quiz-questions"],"_links":{"self":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/26852","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/comments?post=26852"}],"version-history":[{"count":1,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/26852\/revisions"}],"predecessor-version":[{"id":26860,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/26852\/revisions\/26860"}],"wp:attachment":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/media?parent=26852"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/categories?post=26852"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/tags?post=26852"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
