Which of the following solutions do NOT conduct electricity?

Correct option is C

​The correct answer is (c) Alcohol and Glucose

Explanation:

• Electricity conduction in solutions depends on the presence of ions. Substances that ionize in water conduct electricity, while those that do not ionize cannot conduct electricity.
• Alcohol and Glucose do NOT ionize in water, meaning they do not produce free ions to carry electric current. Therefore, they do not conduct electricity.

Information Booster:

• Electrolytes: Substances that dissolve in water and produce ions, allowing electricity to pass through.
• Examples: Acids (HCl, H₂SO₄), Bases (NaOH, KOH), Salts (NaCl, KCl)
• Non-electrolytes: Substances that do not ionize in water and do not conduct electricity.
• Examples: Glucose (C₆H₁₂O₆), Alcohol (C₂H₅OH), Distilled Water

Additional Knowledge:

• (Acid and Base) – Acids and bases ionize in water, releasing H⁺ and OH⁻ ions, respectively, making them good conductors.
