Ionic vs. Polar vs. Nonpolar

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond formed through the transfer of electrons from one atom to another, resulting in the formation of charged ions.

Front

What characterizes polar molecules?

Back

Polar molecules have a partial positive charge on one end and a partial negative charge on the other due to unequal sharing of electrons.

Front

What is a nonpolar molecule?

Back

A nonpolar molecule is a molecule that has an even distribution of electrical charge, meaning it does not have distinct positive or negative poles.

Front

What is the main difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.

Front

What is a property of ionic compounds?

Back

Ionic compounds typically have high melting points and are often soluble in water.

Front

How do polar molecules interact with water?

Back

Polar molecules are hydrophilic, meaning they interact well with water and can dissolve in it.

Front

What is a characteristic of nonpolar substances in water?

Back

Nonpolar substances are hydrophobic, meaning they do not mix well with water and tend to separate.

Front

What happens to ionic compounds when dissolved in water?

Back

Ionic compounds dissociate into their constituent ions when dissolved in water, allowing them to conduct electricity.

Front

What is the significance of electronegativity in bond formation?

Back

Electronegativity determines how strongly an atom attracts electrons; differences in electronegativity between atoms can lead to ionic or polar covalent bonds.

Front

What is a common example of a polar molecule?

Back

Water (H2O) is a common example of a polar molecule due to its bent shape and the difference in electronegativity between hydrogen and oxygen.
