Water has stronger hydrogen bonding, but not stronger hydrogen bonds than HF, but it does have stronger hydrogen bonds than ammonia.
There are two things that affect the intermolecular forces in these molecules: the strength of the H-bond itself, and the number of them that can be formed between neighboring molecules.
The larger the difference in electronegativity of the H atom and the other atom (N, O, and F), the stronger the H-bond. Therefore the order is N < O < F.
However, HF can only form one H-bond to one neighbor, while water can form two thus promoting more intermolecular interactions. Ammonia, while it has 3 N-H bonds, has far weaker H-bonds due to the lower electron density on the N-atom compared to the O-atom in water.

Why is water (H2O) a liquid at room temperature, whereas ammonia (NH3) is a gas at room temperature?
Water and ammonia have different intermolecular forces. Water molecules are held together by hydrogen bonding, which is stronger than the dispersion forces that hold ammonia molecules together. This difference in intermolecular forces results in water being a liquid at room temperature while ammonia is a gas.
Why is water a liquid at room temperature whereas ammonia is a gas at room temperature?
The answer lies in what is know as intermolecular forces. There three basic types: london dispersion forces (which all molecules have), dipole to dipole forces and hydrogen bonding. The stronger these forces the more the molecules have a tendancy to stick together. I listed the forces from weakest to strongest. Since water has hydrogen bonding its intermolecukar forces are the strongest and over powers the atmospheric forces and energies trying to tear the molecules away from eachother. Ammonias intermolecular forces are not strong enough under normal temperature and pressure so the molecules and individual gas molecules.
Water and ammonia both have low vapor pressures compared to other substances like carbon dioxide or hydrogen gas because of?
their relatively weak intermolecular forces. Water and ammonia molecules are attracted to each other through hydrogen bonding, which requires more energy to break compared to the forces between carbon dioxide or hydrogen gas molecules. This results in lower vapor pressures for water and ammonia.
Which of these substances contain molecules that will not form hydrogen bonds hydrogen hydrogen Fluoride Water or Ammonia?
Its hard to answer your question since you did not use commas. But... if the question is hydrogen, hydrogen fluoride, water or Ammonia then.. Hydrogen...is diatomic naturally so I'm not sure which you are referring too. It can not hydrogen bond with its self but it could act as a hydrogen donor and something like an ether could act as the proton acceptor. Then they could both participate in hydrogen bonding. Same answer as above goes from Ammonia. HF, can hydrogen bond with it's self and other molecules containing fluorine, Nitrogen or Oxygen. Same answer as above goes for water.
What is more polar ethanol or water?
Water is more polar than ethanol. This is because water has stronger hydrogen bonding due to the presence of more hydrogen-bonding sites (two hydrogen atoms and one oxygen atom), making it a better solvent for polar substances. Ethanol is also polar but has weaker hydrogen bonding compared to water.
Which has the strongest intermolecular force NH3 or H20?
Water (H2O) has stronger intermolecular forces than ammonia (NH3) due to hydrogen bonding in water molecules. Hydrogen bonding is a type of intermolecular force that is stronger than the dipole-dipole interactions present in ammonia molecules.
Why is water (H2O) a liquid at room temperature whereas ammonia (NH3) is a gas at room temperature?
Hydrogen bonding is stronger in water than in ammonia.

Why water has more boiling point than ammonia and hydroflouric?
Water has a higher boiling point than ammonia and hydrofluoric acid because hydrogen bonding in water molecules is stronger than the dipole-dipole interactions present in ammonia and hydrofluoric acid. The presence of hydrogen bonding allows water molecules to come closer together, requiring more energy to separate them, hence a higher boiling point.
Why does ammonia dissolve more easily in water than in methanol?
Ammonia dissolves more readily in water compared to methanol because of its ability to form hydrogen bonds with water molecules. The hydrogen bonding between ammonia and water helps to stabilize the ammonia molecules in solution, allowing for better dissolution. In comparison, methanol does not form as strong hydrogen bonds with ammonia, resulting in lower solubility.
Is hydrogen bonding strongest between molecules of H20 H2S H2Se or H2Te?
Hydrogen bonding is strongest in molecules of H2O (water) because oxygen is highly electronegative, creating a large difference in electronegativity between the hydrogen and oxygen atoms which strengthens the hydrogen bonding.
Does water gave stronger hydrogen bond than hydrogen fluoride?
Hydrogen fluoride (HF) has a stronger hydrogen bond than water, as HF molecules have a greater electronegativity difference between the hydrogen and fluoride atoms compared to water molecules, resulting in a stronger attraction. This makes hydrogen fluoride a stronger hydrogen bonding compound than water.

In what conditions would hydrogen bonding be present?
Answer this question…When hydrogen is attached to N, F, or O
Does NH3 contain a hydrogen bond?
Yes, ammonia (NH3) can participate in hydrogen bonding. In ammonia, the nitrogen atom can form a hydrogen bond with a hydrogen atom from another ammonia molecule, leading to the formation of a hydrogen bond. Hydrogen bonding in NH3 is weaker compared to molecules like water due to the lower electronegativity difference between nitrogen and hydrogen.
What molecules listed can form hydrogen bonds hydrogen ammonia hydrochloric acid or hydrofluoric?
Ammonia can form hydrogen bonds due to its ability to donate a hydrogen atom and act as a hydrogen bond acceptor. Hydrochloric acid and hydrofluoric acid cannot form hydrogen bonds as they lack hydrogen atoms bound to electronegative atoms like nitrogen, oxygen, or fluorine.
