VSEPR Theory - Oct 19

The acronym VSEPR stand for

• very strong electron pair repulsion.

• varied symmetry electrostatic proton reaction.

• venomous snakes enjoy pink ribbons.

• valence shell electron pair repulsion.

VSEPR theory is used to predict

• the number of unshared pairs of electrons in a Lewis structure.

• the number of multiple bonds in a Lewis structure.

• the three-dimensional geometry of a molecule.

• the three-dimensional crystal lattice structure of ionic compounds.
