For a dilute aqueous solution of glucose,the van't Hoff factor $(i)$ is:

Which of the following compounds has a Van't Hoff factor $i$ equal to $2$ for a dilute solution?

$A$ $0.001 \ molal$ solution of $[Pt(NH_3)_4Cl_4]$ in water has a freezing point depression of $0.0054 \ ^oC$. If $K_f$ for water is $1.80 \ K \ kg \ mol^{-1}$,the correct formulation for the above complex is:

$12.25 \ g$ of $CH_3CH_2CHClCOOH$ is added to $250 \ g$ of water to make a solution. If the dissociation constant of the above acid is $1.44 \times 10^{-3}$,the depression in the freezing point of water in $^{\circ}C$ is ($K_f$ for water is $1.86 \ K \ kg \ mol^{-1}$)

Which of the following pairs has the same freezing point?

Identify the compound amongst the following whose $0.1 \ M$ aqueous solution has the highest boiling point.
