What happens to the boiling point of a substance when its intermolecular forces are weaker?

Back

The boiling point is lower.

Front

Which compound has the strongest intermolecular forces (IMF)?

Back

HOH (water) has the strongest IMF.

Front

In an ionic compound, how are the electrons shared?

Back

Electrons are not shared.

Front

What type of ion is formed when a nonmetal gains two electrons to achieve an octet?

Back

Anion (gains two electrons, nonmetal with a -2 charge).

Front

How can you determine if a molecule is polar or non-polar?

Back

Consider the symmetry and electronegativity of the atoms; non-polar molecules have symmetrical charge distribution.

Front

Define intermolecular forces (IMF).

Back

Intermolecular forces are the forces of attraction or repulsion between neighboring particles (atoms, molecules, or ions).

Front

What is the difference between a cation and an anion?

Back

A cation is a positively charged ion (loses electrons), while an anion is a negatively charged ion (gains electrons).

Front

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons.

Front

What is a polar molecule?

Back

A polar molecule has a net dipole moment due to the presence of polar bonds and an asymmetrical shape.

Front

What is a non-polar molecule?

Back

A non-polar molecule has an even distribution of charge, resulting in no net dipole moment.
