A) \[{{\operatorname{C}}_{6}}{{H}_{5}}N{{H}_{3}}C{{l}^{-}}\]
B) \[\operatorname{Ca}{{\left( N{{O}_{3}} \right)}_{2}}\]
C) \[La{{\left( N{{O}_{3}} \right)}_{2}}\]
D) \[{{\operatorname{C}}_{6}}{{H}_{12}}{{O}_{6}}\]
Correct Answer: D
Solution :
As \[{{\operatorname{C}}_{6}}{{H}_{12}}{{O}_{6}}\]i.e glucose does not dissociate, \[\therefore \Delta {{T}_{f}}\]is minimum or is maximum. \[\Delta {{T}_{f}}\] is the freezing point. \[\Delta {{T}_{f}}= {{k}_{f}}\times m\]B where, m = molality \[{{\operatorname{k}}_{f}}=\]molal depression constant
