Unformatted text preview: Valence Bond (VB) Theory Molecular Shapes and Bonding In the next sections we will use the following terminology: A = central atom B = bonding pairs around central atom U = lone pairs around central atom For example: AB 3 U designates that there are 3 bonding pairs and 1 lone pair around the central atom. Linear Electronic Arrangement:AB 2 Species (No Lone Pairs of Electrons on A) Some examples of molecules with this geometry are: – BeCl 2 , BeBr 2 , BeI 2 , HgCl 2 , CdCl 2 All of these examples are linear, nonpolar molecules....
