As a chemistry expert with a deep understanding of solutions and their properties, I can provide a comprehensive explanation as to why a sucrose solution does not conduct electricity.
First and foremost, it's crucial to understand the basic principles of electrical conductivity. Electrical conductivity in a solution is primarily due to the presence of ions—charged particles—that can move freely and carry an electric current. When a substance dissolves in water and dissociates into its constituent ions, these ions are what enable the solution to conduct electricity.
Now, let's consider sucrose, a common disaccharide composed of glucose and fructose molecules. When sucrose is dissolved in water, it undergoes a physical change but does not undergo a chemical change. This means that the sucrose molecules remain intact and do not break down into smaller charged particles or ions. Since there are no ions present in the solution, there are no charged particles available to move and carry an electric current. This is the fundamental reason why a sucrose solution is non-conductive.
It's important to note that not all molecular substances form non-conductive solutions when dissolved in water. Some substances, like ammonia, can react with water to form ions. When ammonia dissolves in water, it can form ammonium ions (NH4+) and hydroxide ions (OH-) through a process known as ionization. These ions are capable of conducting electricity, which is why an ammonia solution can conduct electricity.
Another factor to consider is the solubility and structure of the solute. Sucrose has a relatively large and complex molecular structure, which does not readily ionize or dissociate in water. In contrast, substances with smaller, more reactive molecules may ionize more readily, leading to the formation of ions and thus a conductive solution.
Furthermore, the strength of the intermolecular forces within the sucrose molecule also plays a role. The hydrogen bonding and other forces that hold the sucrose molecule together are strong enough that they are not easily overcome by the interactions with water molecules, preventing the sucrose from breaking down into ions.
In summary, a sucrose solution does not conduct electricity because it consists of molecules that do not ionize when dissolved in water. The lack of free-moving ions in the solution means there are no charged particles to carry an electric current, resulting in a non-conductive solution. This is in contrast to substances that ionize in water, forming ions that can conduct electricity.

When sugar is dissolved in water, the solution does not conduct electricity, because there are no ions in the solution. Some substances that are made of molecules form solutions that do conduct electricity. Ammonia is such a substance. When ammonia dissolves in water, it reacts with the water and forms a few ions.
