What does VSEPR stand for?

Valence Shell Electron Pair Repulsion

What molecular shape is formed when a central atom has 2 bonds and no lone pairs?

Linear

What molecular shape is formed when a central atom has 3 bonds and no lone pairs?

Trigonal Planar

What molecular shape is formed when a central atom has 4 bonds and no lone pairs?

Tetrahedral

What shape is formed when a central atom has 3 bonds and 1 lone pair?

Trigonal Pyramid

What shape is formed when a central atom has 2 bonds and 1 lone pair?

Bent

What is polarity in molecular terms?

Uneven distribution of electrons in a molecule caused by differences in electronegativity.

What type of bonding occurs between a metal and a nonmetal?

Ionic Bonding

What type of bonding occurs between two different nonmetals?

Polar Covalent Bonding

What type of bonding occurs between two identical nonmetals?

Nonpolar Covalent Bonding

What is a dipole?

A representation that shows which atom attracts electrons more in a polar covalent bond.

Why are hydrocarbons considered nonpolar?

They contain carbon and hydrogen which have very similar electronegativities, resulting in no significant dipoles.

How can a molecule with only polar bonds be nonpolar?

When the shape of the molecule is symmetric, causing individual bond dipoles to cancel each other out.

How can a molecule with only nonpolar bonds be polar?

This can occur if the electron density is uneven due to structure or lone pairs.

What are intermolecular forces (IMF)?

Forces that occur between molecules, affecting physical properties like boiling point and viscosity.

What is viscosity?

The resistance of a fluid to flow.

What is vapor pressure?

The pressure exerted by a vapor in equilibrium with its liquid or solid phase.

What rule is used to determine solubility?

Like dissolves like.

Which type of substances dissolve in water?

Polar substances and ionic compounds.

Give an example of a substance that does not dissolve in water.

Oil

What effect does hydrogen bonding have on boiling points?

Hydrogen bonding increases boiling points.

What is the strongest type of intermolecular force?

Hydrogen bonding
