Given, molality of solution =0.01‌mol‌kg−1
We know that, ∆Tf=iKfm ...(i) ...(where,symbols‌have‌their‌usual‌meaning)
The van't Hoff factor for all given solvent is 1 as they does not ionise. Therefore,
For, Eq(i) ∆Tf∝Kf
Therefore, the depression in freezing point of given solution is highest for carbon tetrachloride because its Kf value is highest.
