Warm-Up Molecular Polarity

What are intramolecular forces?

• Intramolecular forces are responsible for the physical properties of substances.
• Intramolecular forces are the forces between different molecules.
• Intramolecular forces are the forces that occur only in ionic compounds.
• Intramolecular forces are the forces that hold atoms together within a molecule, like a bond.

What are intermolecular forces?

• Intermolecular forces are the forces of attraction or repulsion between neighboring particles.
• Intermolecular forces are the forces that act within a single particle.
• Intermolecular forces are the forces that exist only in solids.
• Intermolecular forces are the forces that only repel particles.
• Intermolecular forces are the forces of attraction between atoms in a compound, like a bond.

What are dipoles?

• Dipoles are pairs of equal and opposite charges or magnetic poles separated by a distance.
• Dipoles are always stationary and do not move.
• Dipoles are single charges with no opposite counterpart.
• Dipoles are only found in magnetic materials.

What are dipole movements?

• Dipole moments are vector quantities that represent the polarity of a molecule, indicating the separation of positive and negative charges.
• Dipole moments are used to calculate the boiling point of substances.
• Dipole moments are scalar quantities that measure temperature changes.
• Dipole moments indicate the mass of a molecule.

What are polar bond?

• Polar bonds are ionic bonds that involve complete electron transfer.
• Polar bonds have no dipole moment due to equal electronegativity.
• Polar bonds are covalent bonds between atoms with different electronegativities, resulting in a dipole moment.
• Polar bonds are formed between identical atoms only.

What are nonpolar bonds?

• Nonpolar bonds are ionic bonds where electrons are transferred between atoms.
• Nonpolar bonds occur only in metallic compounds with free electrons.
• Nonpolar bonds are formed when atoms have a large difference in electronegativity.
• Nonpolar bonds are covalent bonds where electrons are shared equally between atoms.

What are polar moelcules?

• Molecules that are always gases at room temperature
• Polar molecules are molecules with an uneven distribution of charge, resulting in a positive and a negative end.
• Molecules that only contain carbon and hydrogen
• Molecules that have equal distribution of charge throughout

What are nonpolar molecules?

• Nonpolar molecules are molecules with an even distribution of electrical charge and no distinct poles.
• Nonpolar molecules are highly soluble in water.
• Nonpolar molecules are always gases at room temperature.
• Nonpolar molecules have a positive and negative end.

A molecule with a net (a)   is a pole molecule.

A molecule with no net (a)   is a nonpolar molecule.
