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.

∙ 12y agoWater is H2O. Ammonia is NH3. The difference in bond strength lies in the electronegativity of the central atom. In short, Oxygen is more electronegative than Nitrogen. Hence hydrogen bonding is stronger :)

∙ 10y agoBecause the hydrogen bonding in HF is much stronger than the intermolecular bonding in ammonia.

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.
Water and ammonia both have low vapor pressures compared to other substances like carbon dioxide or hydrogen gas because of?
hydrogen bonding~
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.

Which statement explains why H2O has a higher boiling point than N2?
In liquid ammonia one hydrogen atom from an adjacent molecule can form an intermolecular hydrogen bond with the nitrogen atom of the central ammonia molecule. With an average of only one intermolecular bond per ammonia molecule, less thermal energy is required to break the liquid ammonia into individual gas phase molecules. Therefore a lower boiling temperature results. In the case of liquid water, one hydrogen atom from each of two adjacent water molecules can form an intermolecular hydrogen bond with each lone pair on the oxygen atom of the central water molecule. As such, a greater amount of thermal energy is required to break the extensive hydrogen bonding network and a higher boiling temperature results.
Is water fluid because of hydrogen or covalent bonding?
Hydrogen bonding
Is hydrogen bonding a strong covalent bond?
false***Hydrogen bonding is a strong intermolecular force. Not a bond.
It what ways are ammonia salt and water alike?
Both ammonia and water exhibit hydrogen bonding. This is an intermolecular force that holds molecules together to increase their melting and boiling points. Water is a small molecule and really should be a gas at room temperature if you compare it to its nearest chemical relative, hydrogen sulfide. Water is not a gas, thank goodness, but a liquid due to hydrogen bonding.Hydrogen bonding is the interaction of a slightly positively charged hydrogen nucleus with a neighboring slightly negatively charged small electronegative atom like nitrogen, oxygen or fluorine.Ammonia, NH3 and water, H2O both have higher melting points due to hydrogen bonding. In chemistry the general rule is the bigger the molecule the higher its melting point.Ammonia melts at -77oC whereas its bigger relative phosphorus trihydride, PH3, melts at a lower temperature of -133oC.Similarly, water melts at 0oC but rotten egg gas, H2S, melts at -82oC.Both ammonia and water owe their unusually high melting and boiling points to hydrogen bonding.Another similarity between them is that both nitrogen and oxygen have electrons in their outer energy level that are not used to make a bond in water and ammonia. These are called lone pairs or non bonding pairs. Oxygen has two non bonding pairs and nitrogen has one non bonding pairs. This makes both water and ammonia attractive to hydrogen ions, H+(also called protons).
Can alcohol mix more easily with fat than water?
no alcohol can not mix more easily with fats than water. this happens because in water- alcohol mixing hydrogen bonding is involved which mixes water readily with alcohol....while during fats- alcohol mixing there is no involvement of hydrogen bonding or any other stronger bonding due to oxidation which causes fats to lose its effective number of hydrogen.
Does water gave stronger hydrogen bond than hydrogen fluoride?
water has stronger hydrogen bond
Why hydrogen bond in water is stronger than in HF and NH3?
In HF molecule hydrogen bonding is the strongest. The reason is that the partial positively charged hydrogen atom is entrapped between the two highly electronegative fluorine atoms.
