In an ideal trigonal planar species, all three ligands are identical and all bond angles are 120°. A trigonal pyramidal has 4 VESPER pairs meaning its VESPER shape is Tetrahedral because it is trigonal pyramidal means you have one lone pair of electrons (those 2 dots) so its AX3E . The central atom in a trigonal pyramidal is at the apex, whereas the other three atoms are at the base, with a bond angle of about 107 degrees. Post by Lisa Leung 2H » Wed Oct 28, 2015 9:33 pm . If you were to remove 2 bonds from an Octahedral molecule and 1 bond from a Square Pyramidal molecule, it would form a square planar shape. Note: for bent molecular geometry when the electron-pair geometry is trigonal planar the bond angle is slightly less than 120 degrees, around 118 degrees. • In trigonal planar, there are no lone pair electrons in the central atom. There is one central atom and the other three atoms (peripheral atoms) are connected to the central atom in a way that they are in the corners of a triangle. Ammonia, chlorate ion, and sulfite ion are some of the examples showing this geometry. Some examples are SO3 (sulfur trioxide), CO3^-2 (the carbonate ion), NO3^-1 (the nitrate ion), and BF3 (boron trifluoride). Since the lone pair- bond repulsion is greater than the bond – bond repulsion, the bonded three atoms and the lone pair will be far apart as possible.
