Linear electron pair geometry would be described as two groups of electrons lying in a straight line. A linear molecule composed of three atoms would be described as having a bond angle of 180o. Carbon dioxide (CO2) is an example of a molecule characterized by linear electron pair geometry. It is composed of one carbon and two oxygens lying in a straight line. In the following structural formula of carbon dioxide arrows are pointing to the two groups of electrons around the central carbon atom.
