Check for Understanding - Intramolecular Forces

Front

What are intramolecular forces?

Back

Intramolecular forces are the forces that hold atoms together within a molecule, including ionic and covalent bonds.

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions, typically between a metal and a nonmetal.

Front

What is a covalent bond?

Back

A covalent bond is a type of chemical bond where two atoms share one or more pairs of electrons, usually between nonmetals.

Front

How can you determine if a compound is ionic or covalent based on conductivity?

Back

Ionic compounds conduct electricity when dissolved in water because they dissociate into ions, while covalent compounds do not conduct electricity.

Front

Why do ionic compounds dissolve in water?

Back

Ionic compounds dissolve in water because they are polar and the positive and negative ions are attracted to the polar water molecules.

Front

What is the relationship between bond type and melting/boiling points?

Back

Ionic compounds generally have higher melting and boiling points than covalent compounds due to the strong electrostatic forces between ions.

Front

What are the properties of ionic compounds?

Back

Ionic compounds typically have high melting and boiling points, are soluble in water, and conduct electricity when dissolved.

Front

What are the properties of covalent compounds?

Back

Covalent compounds usually have lower melting and boiling points, are often not soluble in water, and do not conduct electricity.

Front

What is the significance of polarity in molecules?

Back

Polarity affects the solubility of substances; polar molecules tend to dissolve in polar solvents like water, while nonpolar molecules do not.

Front

What is an example of a substance with ionic bonds?

Back

Sodium chloride (NaCl) is an example of a substance with ionic bonds.
