This is an example of a Bent molecule that contains 1 lone pair. The lone pair is located at the top of the molecule, forcing the other atoms to move down and create a 118° angle between them in a 2-dimensional structure. There must also be a double bond in order to complete the octect rule for the central atom. This particular molecule isSelenium Oxide, SeO2. The lewis dot structure is composed of 18 valence electrons, 2 bonding locations, and 1 lone pair on the central atom.
