The sulfur trioxide molecule (SO\u2083) consists of one sulfur (S) atom centrally bonded to three oxygen (O) atoms. Each S=O bond in SO\u2083 involves a double bond. Therefore, there are three bonding pairs of electrons and no lone pairs around the central sulfur atom.<\/li>\n\n\n\n
The VSEPR theory predicts that electron pairs around a central atom will arrange themselves as far apart as possible to minimize electron pair repulsion. In SO\u2083, the sulfur atom has three bonding regions and no lone pairs. The three bonding pairs will arrange themselves in a way that maximizes their separation.<\/li>\n\n\n\n
With three bonding pairs and no lone pairs, the geometry of the SO\u2083 molecule is trigonal planar<\/strong>. In this arrangement, the three oxygen atoms are positioned at 120\u00b0 angles from each other, lying in the same plane around the central sulfur atom.<\/li>\n\n\n\n
In a trigonal planar structure, all the bond angles between the atoms are 120\u00b0. The molecule is flat and symmetric, which is typical for molecules with a trigonal planar geometry.<\/li>\n\n\n\n
The absence of lone pairs on the central sulfur atom helps maintain the ideal bond angles of 120\u00b0 and the symmetrical trigonal planar shape.<\/li>\n<\/ol>\n\n\n\n![\"\"](\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner6-384.jpeg\")
