What is the electron domain geometry and bond angle of a molecule with 2 domains?
Linear; 180 degrees
When a molecule has 2 electron domains, it can have two possible shapes based on the type of electron domains present in it.
If the two electron domains are both bonding pairs or both lone pairs, the electron domain geometry would be linear, and the bond angle would be 180 degrees.
If the two electron domains are one bonding pair and one lone pair, the electron domain geometry would be bent or angular, and the bond angle would be less than 180 degrees due to the repulsion between the bonding and lone pair. The exact bond angle would depend on the specific molecule and the nature of the electron domains.
Examples of molecules with 2 electron domains include BeCl2, CO2, and H2O, among others.
