The unhybridized p-orbital of carbon forms the pi () bond with this oxygen atom in C=O via p-p overlap. If more than one arrangement of lone pairs and chemical bonds is possible, choose the one that will minimize repulsions, remembering that lone pairs occupy more space than multiple bonds, which occupy more space than single bonds. A. Trigonal pyramidal B. The three O-atoms bonded to the central C-atom lie in the same plane, in a symmetrical arrangement. Repulsion between electrons is minimized when the oxygen atoms form an equilateral triangle around the carbon atom. Once you have the complete molecule, rotate it to examine the predicted molecular structure. The theory is also known as Gillespie-Nyholm theory, after the two scientists who . Such is the case for ozone ( O 3 ), an allotrope of oxygen with a V-shaped structure and an O-O-O angle of 117.5. The structure that includes only the placement of the atoms in the molecule is called the molecular structure. This is because the movement of a bondingelectron pair is limited to the region between the atoms forming the bond, while the lone pair can move more freely. a. tetrahedral b. trigonal planar c. trigonal pyramidal d. trigonal bipyramidal e. seesaw.
