**Chemistry: Lewis Structures and Molecular Shapes**A compound designated as AB₃ has a total valence electrons of 24. Elements A and B are from Group 6A with Element A being less electronegative than Element B. Element A can have an expanded octet.### Questions:7. a) Using the letters A and B, draw the best Lewis structure and any associated resonance structures. *(Note: Please provide a detailed drawing or diagram of the Lewis structure here, representing all valence electrons, bonds, and possible resonance structures.)*b) What is the molecular shape of your structure?c) From your structure in part a, what is the hybridization of the central atom?---This section will guide you through understanding and visualizing the chemical bonding and structural arrangement of the compound AB₃. The compound's characteristics imply that Element A, being less electronegative, will be in the central position, and it is capable of an expanded octet.1. **Drawing Lewis Structures:** Begin by counting the total valence electrons and distributing them to satisfy the octet rule while accommodating the possibility of resonance structures. 2. **Determining Molecular Shape:** Use VSEPR theory (Valence Shell Electron Pair Repulsion) to predict the 3-dimensional arrangement of atoms around the central atom.3. **Hybridization:** Analyze the bonding and lone pairs on the central atom to determine the type of hybridization.This tutorial will reinforce your understanding of chemical bonding concepts and molecular geometry, essential for predicting molecular behavior and reactivity.
