question
According to the Valence Shell Electron Pair Repulsion (VSEPR) theory, a molecule that has five electron groups around the central atom will have what basic geometry?
answer
Trigonal bipyramidal
question
VSEPR theory includes two types of geometries: electron geometry and molecular geometry. What is the difference between the two geometries?
answer
Electron geometry describes the arrangement of the electron groups in a molecule, whereas the molecular geometry describes the arrangement of the atoms.
