Question

Which of the following will have the highest boiling point at `1 atm` pressure?
A. `0.1 M NaCl`
B. `0.1 M sucrose`
C. `0.1 M BaCl_(2)`
D. `0.1 M glucose`

Answer 1

Correct Answer - C
`DeltaT_(b)=K_(b) xx Molality xx (1- alpha + xalpha + yalpha)`
`DeltaT_(b)` is more `BaCl_(2)` as it gives more number of ions,
`(1- alpha + xalpha + yalpha)` is more for `BaCl_(2)` (it is 3).
