WebSolution. Verified by Toppr. The order of the boiling point is H 2O>NH 3>HCl. The extent of Hydrogen bonding is H 2O>NH 3>HCl. Each water molecule can potentially form four hydrogen bonds with surrounding water molecules. There are exactly the right numbers of hydrogens and lone pairs so that every one of them can be involved in hydrogen bonding. http://faculty.ung.edu/altomlinson/General%20Chemistry%20Files/Chapter%2011%20-%20Liquids%20&%20Intermolecular%20Forces/In%20Class%20Exercise%20for%20Chapter%2011%20key.pdf
WebBoth the boiling point elevation and the freezing point depression are related to the molality of the solution. Looking at the formula for the boiling point elevation and freezing point depression, we see similarities between the two. The equation used to calculate the increase in the boiling point is: ΔTb = kb ⋅ m ⋅ i.
