1. Use the information for the structure of A3Z to answer the following questions. Note: A has 7 valence electrons and Z has 5 valence electrons. The A-Z bond is polar. What is the bond angle? BI U X₂ X² Is the molecule polar? 109 What is the electron pair geometry? What is the molecular shape? What is the hybridization? BIUX, X² | BIU X₂ X² Type the molecular shape BIU X₂ X² Type the hybridization Polar O Non-Polar

7.Draw the Lewis structure first, then predict the molecular shape and electron group geometry for each of the following: CS2 H3O+ PBr3 SiCl4

A. F3CCH3 Step 1. Draw the lewis structure Step 2. Description of shape: Central Atom 1= ___ Electron groups = ___ ____ non bonding= ____ total Central Atom 2= ___ Electron groups = ___ ____ non bonding= ____ total Electron group arrangement for central atom 1: Electron group arrangement for central atom 2: Geometry (shape) around central atom 1: Geometry (shape) around central atom 2: Step 3: List and Name all bond angles and give the degree.
