Aqueous solution of which of the following compounds is the best conductor of electric current?
A
Ammonia, $NH_3$
B
Fructose, $C_6H_{12}O_6$
C
Acetic acid, $C_2H_4O_2$
D
Hydrochloric acid, HCl
Detailed Solution
HCl is a strong acid and dissociates completely into ions in water, so its aqueous solution is the best conductor.
Ammonia and acetic acid are weak electrolytes, and fructose is a non-electrolyte.
