1.4 VESPER Theory Flashcards
what does VSEPR stand for
valence shell electron pair reposition
VSEPR theory says…
the most stable three dimensional structure for a molecule is the one in which valence electron pairs are as far apart as possible
what happens to structure geometry as a result of how many groups because of VSEPR theory
the geometry around the atom is directed by how many groups are attached to them
when does linear geometry occur
if theres two groups around a central object (like and atom) then maximizing the distance between those groups leads to linear
what is the distance between the two groups around a central atom (linear)
180 degrees
when does a trigonal planar happen
if there is three groups around the central atom
what is the distance between a trigonal planer
120 degrees
what is a molecule called when there is four groups around the central group
tetrahedral geometry
what is the distance between groups in a tetrahedral
109 degrees
