Vander Waals Force

• A theory that states the shapes of molecules are dictated by the repulsion of the shared/unshared pairs of electrons.

• Bond in which two atoms share three pairs of electrons.

• A weak electrostatic force that attracts neutral molecules to one another.

A theory that states the shapes of molecules are dictated by the repulsion of the shared/unshared pairs of electrons.

• Triple Covalent Bond

• VESPR Theory

• Valence Electron

Unshared Pair

• A bond formed between two atoms in which electrons are shared equally.

• An atom with one or more unpaired electrons.

• Pair of valence electrons that are not shared with another atom in a covalent bond.

Triple Covalent Bond

• A polyhedral angle of four angles. (109.5 degrees)

• Bond in which two atoms share three pairs of electrons.

• A formula that shows the arrangement of atoms in the molecule of a compound.

A polyhedral angle of four angles. (109.5 degrees)

• Structural Formula 

• Tetrahedral Angle

Structural Formula = A formula that shows the arrangement of atoms in the molecule of a compound.

• True

• False

What is the VESPR Theory?

• A weak electrostatic force that attracts neutral molecules to one another.

• A theory that states the shapes of molecules are dictated by the repulsion of the shared/unshared pairs of electrons.

• Temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles.

A bond formed by sharing of one electron pair between two atoms is a...

• Single Covalent Bond

• Sigma Bond

• Double Covalent Bond

A Sigma Bond is A bond formed by the overlap of orbitals in a side-by-side fashion.

• Yes, this is true

• No, A sigma bond is a bond formed by the overlap of orbitals, with the electron density concentrated between the nuclei of the bonding atoms.
