Sucrose is a non-electrolyte. Here's why:

* Electrolytes are substances that dissolve in water and produce ions (charged particles). These ions can conduct electricity.

* Non-electrolytes dissolve in water but do not produce ions. They do not conduct electricity.

Sucrose, when dissolved in water, does not break down into ions. It stays as a single molecule. Therefore, it doesn't conduct electricity and is considered a non-electrolyte.
