There are regions of the sucrose molecule that have polarity, or partial positive and negative charges

There are regions of the sucrose molecule that have polarity, or partial positive and negative charges.

Sucrose molecules are closely associated with each other because of the polar regions in the molecule. When sucrose is placed in water, water molecules are attracted to these polar regions.

Water molecules surround the sucrose molecules, causing them to separate from each other and thereby dissolve.

Unlike , sucrose molecules do not break up. Dissolving occurs because the sucrose molecules separate from each other.
