Which of the molecules has trigonal bipyramidal geometry with bond angles 120 and 90? A molecule with a steric number of 5 can have a trigonal bipyramidal shape. The steric number can be found by adding up the number of bonds and lone pairs coming from the central atom of a molecule (lon...
For covalently bonded molecules and ions containing a central atom and one or more lone electron pairs, oxygen atoms, or sulfur atoms, bond angles can be predicted to within a few degrees by means of an electrostatic model. The parameters required are an electrostatic repulsion number (ERN) ...
Recognize the difference between electron and molecular geometry. Name molecule and electron geometries for molecules with up to six electron groups surrounding a central atom. Compare bond angle predictions from the VSEPR-based model to real molecules. Describe how lone pairs affect bond angles in re...
The molecular geometries of molecules change when the central atom has one or more lone pairs of electrons. The total number of electron pairs, both bonding pairs and lone pairs, leads to what is called theelectron domaingeometry.When one or more of the bonding pairs of electrons is replaced...

- In chemistry, the linear molecular geometry describes the geometry around a central atom bonded to two other atoms (or ligands) placed at a bond-angle of 180°. - Linear organic molecules, such as acetylene (HC≡CH), are often described by invoking sp orbital hybridization for their carbon...
Use VSEPR to predict bond angles about each atom of carbon, nitrogen, and oxygen in these molecules.What is the molecular shape of BrF3 as predicted by the VSEPR theory?Predict the molecular geometry of the compound OF2 using VSEPR.Use the Vsepr ...
What is the relationship between the dipole moment and band moment? How is it possible to have bond moments and yet be nonpolar? Which bond does not have a dipole moment? a) N-H b) O-H c) F-H d) O-O e) S-H Which of the following molecules have...
Intermolecular forces between polar molecules ion-dipole forces are attractive forces between an ion and a polar molecule Hydrogen bonds are strongest intermolecular forces only when H is bond to one of the following ( F,O,N) dipole-induced dipole interaction ...
