Practice 3.6 Polarity

Front

What type of molecule is H2O?

Back

Polar

Front

Why do water molecules stick together?

Back

One side has a positive charge and the other side has a negative charge.

Front

What type of compounds can water NOT dissolve?

Back

Nonpolar Compounds

Front

What is the correct chemical formula for water?

Back

H2O

Front

Which part of a water molecule has a positive charge?

Back

The Hydrogen.

Front

Define a polar molecule.

Back

A molecule with a net dipole moment due to the presence of polar bonds, resulting in a positive and negative end.

Front

What is the significance of hydrogen bonding in water?

Back

Hydrogen bonding leads to water's unique properties, such as high surface tension and boiling point.

Front

What is a nonpolar molecule?

Back

A molecule that does not have distinct positive and negative ends, resulting in no net dipole moment.

Front

Give an example of a polar compound.

Back

Water (H2O) is a common example of a polar compound.

Front

What is the role of oxygen in a water molecule?

Back

Oxygen is more electronegative than hydrogen, creating a partial negative charge on the oxygen atom.
