Answer : Carbon tetrachloride,
will show the greatest freezing point lowering.
Explanation :
For non-electrolyte solution, the formula used for lowering in freezing point is,
![\Delta T_f=k_f\times m](https://tex.z-dn.net/?f=%5CDelta%20T_f%3Dk_f%5Ctimes%20m)
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.
They have low boiling points
