Question

List I List II

A) Electronic conductors 1) Acetic acid

B) Electrolytic conductors 2) Solid salts

C) Non-electrolyte 3) Sucrose

D) Weak electrolyte 4) Molten salts

Write the combination for A B C D (respectively) :

• A. 2 1 3 4
• B. 2 4 3 1
• C. 1 4 3 2
• D. 4 3 2 1

Answer 1

The correct option is B 2 4 3 1

Acetie acid is a weak electrolyte as being a weak acid it does not dissociate fully.

Sucrose does not dissociate into ions. Therefore, it is a non-electrolyte.

Solid-salts do not conduct electricity due to absence of free ions to carry charge whereas molten salts can conduct electricity as ions are free to move.

Option B is correct.
