Choose the solvent below that would show the greatest freezing point lowering when used to make a 0.20 m nonelectrolyte solution. diethyl ether, kf = 1.79°c/m benzene, kf = 5.12°c/m chloroform, kf = 4.70°c/m ethanol, kf = 1.99°c/m carbon tetrachloride, kf = 29.9°c/m

Answer : Carbon tetrachloride, will show the greatest freezing point lowering.

Explanation :

For non-electrolyte solution, the formula used for lowering in freezing point is,

where,

= lowering in freezing point

= molal depression constant

m = molality

As per question, the molality is same for all the non-electrolyte solution. So, the lowering in freezing point is depend on the only.

That means the higher the value of , the higher will be the freezing point lowering.

From the given non-electrolyte solutions, the value of of carbon tetrachloride is higher than the other solutions.

Therefore, Carbon tetrachloride, will show the greatest freezing point lowering.

the only liquid elements at standard temperature and pressure are bromine (br) and mercury (hg). although, elements caesium (cs), rubidium (rb), francium (fr) and gallium (ga) become liquid at or just above room temperature.
