<u>Explanation:</u>
It is given that polar solutes can be dissolved in polar solvents and non-polar solutes can be dissolved in non-polar solvent.
Alcohol being polar, does not dissolves ionic salt in it.
is a non-polar solvent.
From the given options:
1. NaCl: This is an ionic salt and hence, it will be soluble in water only.
2. : Iodine gas is a non-polar solute and hence, will be dissolved in non-polar solvent which is
3. Ethanol: As, it is a polar molecule and is not an ionic salt, therefore it can be soluble in both water and alcohol.
4. Benzene: It is a non-polar molecule and hence, it will be dissolved in
5. : Bromine gas is a non-polar solute and hence, will be dissolved in
6. : This is an ionic salt and hence, it will be soluble in water only.
7. Toluene: This is a non-polar solute and hence, will be dissolved in
8. : This is an ionic salt and hence, it will be soluble in water only.
