Final answer:
C12H22O11, known as sucrose, is a non-electrolyte because it does not ionize or dissociate into ions in water.
Step-by-step explanation:
The compound C12H22O11 is not a strong acid, weak acid, strong base, or weak base; it is a type of sugar known as sucrose, which is a non-electrolyte.
Non-electrolytes do not ionize in water, meaning they do not produce ions that conduct electricity in solution. Sucrose is composed of glucose and fructose and does not dissociate into ions when dissolved in water. Therefore, option 5) non-electrolyte correctly classifies the nature of the compound C12H22O11.
