Webb6 sep. 2024 · HF has a higher boiling point than NH 3 because the H-bonds in HF are stronger than those in NH 3. What is the intermolecular force of F2? As both fluorine … Webb23 apr. 2011 · 1 answer. NaCl should be the highest because NaCl is an ionic compound and those boil at higher temperatures due to breaking the lattice energy of the crystal etc. The lowest should be F2 since there is no hydrogen bonding involved. Both HCl and HF have higher boiling points due to hydrogen bonding and should fall between the two …

HF has the higher boiling point because hydrogen bonding ; The order of the boiling points for the hydrogen halides, except for HF, is HI > HBr > HCl. The reason for this order can be attributed to: a) the relative covalent bond strengths b) differences in hy; What is the Delta H of HF (hydrogen fluoride)? Choose the substance with the ...
WebbSecond, we notice that, with the exceptions of NH 3, H 2 O, and HF, the boiling points of the hydrides always increase in a single group as we go down the periodic table: for example, in Group IV, the boiling points increase in the order CH 4 WebbThe 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.
WebbHF SnH GeH 4 4 SiH 4 CH 4 Boiling point (deg. Celcius) Period It is apparent from this figure that: - the tetrahydrides have lower boiling points than the monohydrides, - the boiling points increase with period, with the exception of HF. Explain these features. Marks 4 Boiling points depend on the strength of the intermolecular forces.

WebbHF can refer to both hydrogen fluoride (gas) and hydrofluoric acid. Hydrofluoric acid is a solution of hydrogen fluoride (HF) in water.It is a precursor to almost all fluorine compounds, including pharmaceuticals such as fluoxetine (), surface coatings such as PTFE (), and elemental fluorine itself. Hydrofluoric acid is classified as a weak acid … finalists at westminster dog showWebbIn case of HF, difference in electronegativity of hydrogen and fluorine is greater. Hence HF molecule is highly polarized, due to this ,molecules are associated strongly by strong intermolecular hydrogen bonds.Thus higher boiling point is recorded for HF. gsa students associationWebb7 juli 2024 · Which has higher boiling point HBr or HF? We can conclude, the order of boiling point followed is HF > HI > HBr > HCl. …. The reason is the presence of strong hydrogen bonding in the HF, as hydrogen intermolecular interactions are greater than the van der Waals forces.
