• 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. For trigonal pyramidal geometry the bond angle is slightly less than 109.5 degrees, around 107 degrees.

For trigonal pyramidal geometry the bond angle is slightly less than 109.5 degrees, around 107 degrees. VSEPR explains a lot about molecular geometry and structure, BUT NOT EVERYTHING!! The electrons (both in pairs and singles as you will see) are "attached" to a central atom in the molecule and can "pivot" freely on the atom's surface to move away from the other electrons. Electrons will come in several flavors:
• However, molecular geometry is determined solely on the basis of bonding electron pairs, not the number of electron pair, whereas electron geometry is determined on the basis of both bonding electron pairs and lone electron pairs. When no lone pairs of electrons are present in a molecule, the electron geometry is same as the molecular shape.

• There are 4 regions of electron density, 4 orbitals, around the central carbon atom; therefore..... And therefore, the electronic geometry will be tetrahedral. Since all of these electron pairs represent C-H bonds, the molecular geometry will also be tetrahedral with /_H-C-H=109.5^@. Yea just struggle with the geometry of the molecule in specific. I know you have to look at the bonding and non-bonding electron pairs and determine the shape, but not sure as to how this actually works. Still cant differentiate between trigonal pyramidal and trigonal bipyramidal.
• In coordination chemistry, a ligand is an ion or molecule (functional group) that binds to a central metal atom to form a coordination complex. The bonding with the metal generally involves formal donation of one or more of the ligand's electron pairs. The nature of metal–ligand bonding can range from covalent to ionic.

MOLECULAR GEOMETRY OR MOLECULAR SHAPE The determination of molecular shape involves determining BOND ANGLES. We are going to use a very simple theory of molecular shape which only requires Lewis electron dot structures and simple electrostatic ideas; this is called Valence Shell Electron Pair Repulsion Theory (VSEPR) The geometry of where electrons are in relation to a central atom. Electron pairs in four locations will repel and end up 109.5o apart, three locations 120o, two locations 180o and one location no separation of electrons. Molecular shape: Trigonal Pyramidal .

But – IF an electron group is a lone pair, then there is no atom visible to “mark that corner” of the geometry. Thus the “Electron Group Geometry” is determined by the number of groups of electrons and the arrangement of those groups around the central atom. But the “Molecular Geometry” depends on whether or not there is an atom ...

The shapes of these molecules can be predicted from their Lewis structures, however, with a model developed about 30 years ago, known as the valence-shell electron-pair repulsion (VSEPR) theory.

Essentially, electron geometry includes lone pairs while molecular geometry excludes lone pairs in the VSEPR chart. 2 , so the resulting molecular geometry or shape of the molecule is also linear. Consider BCl. 3 , for which the Lewis dot structure is This has three pairs around the central B atom. Electron-pair repulsions are minimized by placing these three pairs at 120o apart in a plane, called a trigonal planar arrangement.

However, with electron geometry (steric number) lone pairs and bonds are treated the same. You also treat double and triple bonds as one group instead of 3 just like you did in molecular shape. You also treat double and triple bonds as one group instead of 3 just like you did in molecular shape.
