1.	Which of the following solution will have highest boiling point ?A. 0.1 M `FeCl_(3)`B. `0.1M BaCl_(2)`C. `0.1MNaCl`D. 0.1 M urea `(NH_(2)CONH_(2))`
Answer» Correct Answer - A Elevation in boiling point is a colligative propert, ie, depends only on nump or ions 0.1 `FeCI_(3)` gives maximum number of ions, thus has highest bioling point
