One of the bonds is a double bond and the other two are single bonds, with one lone pair on the sulfur atom. The negative charge is delocalized across the oxygen atoms, which can each carry a negative formal charge.<\/li>\n\n\n\n<li><strong>Electron Pair Geometry<\/strong>: Trigonal planar. This is because the sulfur atom has three regions of electron density (3 bonding pairs of electrons), which pushes the bonds into a trigonal planar arrangement.<\/li>\n\n\n\n<li><strong>Molecular Geometry<\/strong>: Trigonal planar as well, because there are no lone pairs of electrons on the central sulfur atom that would distort the geometry.<\/li>\n\n\n\n<li><strong>Bond Angles<\/strong>: Approximately 120\u00b0, typical for a trigonal planar structure.<\/li>\n\n\n\n<li><strong>Polar or Nonpolar<\/strong>: <strong>Nonpolar<\/strong>. The molecule is symmetrical, and the dipoles from each oxygen bond cancel out due to the symmetrical arrangement of the oxygens around the sulfur atom.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">2. <strong>SF\u2084 (Sulfur Tetrafluoride)<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Lewis Structure<\/strong>: SF\u2084 consists of a sulfur atom surrounded by four fluorine atoms. One of the fluorine atoms is connected to the sulfur with a single bond, and there are lone pairs of electrons on both sulfur and fluorine. Sulfur has one lone pair of electrons that forms an axial position.<\/li>\n\n\n\n<li><strong>Electron Pair Geometry<\/strong>: Trigonal bipyramidal. Sulfur has five regions of electron density\u2014four bonding pairs from the fluorine atoms and one lone pair of electrons.<\/li>\n\n\n\n<li><strong>Molecular Geometry<\/strong>: See-saw. The lone pair of electrons occupies one of the equatorial positions, which leads to a distorted shape from the trigonal bipyramidal geometry.<\/li>\n\n\n\n<li><strong>Bond Angles<\/strong>: The axial fluorine atoms have bond angles of about 90\u00b0, and the equatorial fluorine atoms are at approximately 120\u00b0 to each other.<\/li>\n\n\n\n<li><strong>Polar or Nonpolar<\/strong>: <strong>Polar<\/strong>. Due to the asymmetric arrangement of fluorine atoms and the lone pair on sulfur, the dipoles do not cancel out, resulting in a net dipole moment.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">3. <strong>KrBr\u2082 (Krypton Dibromide)<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Lewis Structure<\/strong>: KrBr\u2082 consists of a krypton atom at the center with two bromine atoms attached. Krypton is a noble gas, so it typically forms two bonds in compounds like KrBr\u2082, and it does not have lone pairs of electrons.<\/li>\n\n\n\n<li><strong>Electron Pair Geometry<\/strong>: Linear. Krypton has two bonding regions (from the two bromine atoms), which leads to a linear geometry.<\/li>\n\n\n\n<li><strong>Molecular Geometry<\/strong>: Linear. This matches the electron pair geometry as there are no lone pairs on krypton.<\/li>\n\n\n\n<li><strong>Bond Angles<\/strong>: 180\u00b0, which is typical for a linear molecule.<\/li>\n\n\n\n<li><strong>Polar or Nonpolar<\/strong>: <strong>Nonpolar<\/strong>. The molecule is symmetrical because both bromine atoms are positioned symmetrically on either side of krypton. The dipoles cancel each other out, so the molecule is nonpolar.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Summary:<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>SO\u2083\u00b2\u207b<\/strong>: Nonpolar, trigonal planar, 120\u00b0 bond angles<\/li>\n\n\n\n<li><strong>SF\u2084<\/strong>: Polar, see-saw, 90\u00b0 and 120\u00b0 bond angles<\/li>\n\n\n\n<li><strong>KrBr\u2082<\/strong>: Nonpolar, linear, 180\u00b0 bond angles<\/li>\n<\/ul>\n\n\n\n<p>This breakdown shows how to approach each molecule by considering the Lewis structure, geometry, and overall molecular polarity.<\/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-banner5-898.jpeg\" alt=\"\" class=\"wp-image-246608\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>For the following elements, provide the 3D Lewis structure, Electron pair geometry, Molecular geometry, Bond angle(s), and indicate whether it is Polar or Nonpolar.
