Question

Which among the following substance does not conduct electricity in its aqueous solution state?

• A. Glucose
• B. Alcohol
• C. Hydrochloric acid
• D. Common salt

Answer 1

Answer: (A), (B)

The correct options are
A Glucose
B Alcohol

Glucose and alcohol does not conduct electricity in its aqueous solution state. Glucose and alcohol are non-electrolytes. They do not dissociate in aqueous solution. No current carrying ions are produced. On the other hand, hydrochloric acid and common salt $\left(NaCl\right)$ are strong electrolytes. They completely dissociate in aqueous solution and produce current carrying ions. Hence, hydrochloric acid and common salt conduct electricity in its aqueous solution state.
