Polarity & Such
the 3 dimensional arrangement of atoms in space
What is their molecular geometry?
this theory states that the repulsion between the sets of valence-level electrons surrounding an atom causes these sets to be oriented as far apart as possible
What is VSEPR Theory?
The molecular geometry of BF2
What is a linear molecule?
the model showing the mixing of two or more atomic orbitals of similar energies on the same atom to produce new hybrid atomic orbitals of equal energies
What is hybridization?
created by equal but opposite charges that are separated by a short distance
What is a dipole?
◦the polarity of each bond along with its geometry determine the uneven distribution of molecular charge
what is molecular polarity?
This is what VSEPR Theory stands for.
What is "Valence Shell Electron Pair Repulsion"
The molecular geometry of SF3
tee-shaped
orbitals of equal energy produced by the combination of two or more orbitals of the same atom
What are hybrid orbitals?
The strongest Intermolecular forces exist between these molecules
What are polar molecules?
a term for two bonded molecules
what is a diatomic molecule?

This is why ______________ is a good measure of the force of attraction between particles of a liquid
What is boiling point?
The forces of attraction between polar molecules are known as this
What are dipole-dipole forces?
After performing many tests designed to reveal the shapes of different molecules, chemists developed 2 different, equally successful theories to explain certain aspects of their findings.
One theory accounts for molecular _______ that influences shape
What is a bond angle?
These are treated similarly to molecules but you must remember to consider all of the electron pairs present in any ion or molecule
What are polyatomic ions?
The molecular geometry of NH3
What is a pyramid with a triangular base?
To achieve four equivalent bonds, carbon’s 2s and three 2p orbitals hybridize to form four new, identical orbitals called this.
what is sp3
This is the definition of dipole-dipole forces
What are Dipole-dipole forces are attractive forces between the positive end of one polar molecule and the negative end of another polar molecule?
To predict the geometries of more-complicated molecules, one must consider the locations of all ___________
What are electron pairs?
VSEPR Theory does not explain this important part of molecular geometry.
What is the relationship between a molecule’s geometry and the orbitals occupied by its bonding electrons?
The molecular geometry of BrF5
What is octahedral?
The forces of attraction between molecules
What are intermolecular forces?
These forces are short-range forces, acting only between nearby molecules
What are dipole-dipole forces?
