Pre-lecture Reading Assignment: Bonding & Geometry

Quick Intro

We need to understand the geometry (or shape) of molecules to understand some of their physical properties and some aspects of their chemical reactivity. To understand the geometry of molecules, we first have to understand the types of bonds present. We will need to think about the types of orbitals used to make the bonds to understand the types of bonds and the geometries. 

 

Objectives

• Predict geometries around atoms in a molecule.
• Predict polarity of molecules based on bonding and shape.
• Identify types of bonds in a molecule (sigma, pi).
• Identify types of orbitals used to make bonds.
