Hydrogen Bonds In a compound, there may be atoms with different levels of attraction to electrons. This attraction is called "electronegativity." If one atom in a compound "likes" electrons more (and has a higher electronegativity), the electrons shared between the molecules will spend more time on the atom with a higher electronegativity. Because electrons are negative, the atom that has a stronger attraction will be slightly negative (δ−) while the other atoms will be slightly positive (δ+). In all compounds that have hydrogen bonds, the hydrogen atom(s) is/are the positive atom and the other atom (usually nitrogen, fluorine, or oxygen) is the electronegative negative one.

This slight polarity on the molecule allows it to interact with other molecules of similar charge. The negative atom of one molecule (like nitrogen, fluorine, or oxygen) will bind to the positive hydrogen in another molecule. The bond between the two is a hydrogen bond. It is not a strong bond like a covalent, nor does it actually involve the transfer of electrons, but it does cause two molecules to "stick" together.

The classic (and the most important) case of hydrogen bonding is with water. There are a number of emergent properties of water that are due to the hydrogen bonds, one of which is floating ice. To see an explanation of the hydrogen bonds at work that cause ice to float, see the related question in the "Related Questions" section below.

What is hydrogen bond?

It is a type of bond that involves the attractive interaction of a hydrogen atom and an electronegative atom. For example (nitrogen, oxygen or fluorine). This type of bond is weaker than covalent and ionic bonds but stronger than van der Waals. I hope this helps.

What elements are bonded to hydrogen in hydrogen bonding?

Fluorine, oxygen, nitrogen and carbon only. The first three are very electronegative elements bond with hydrogen to form hydrogen bonding. Carbon can also participate in hydrogen bonding, especially when the carbon atom is bound to several electronegative atoms, as is the case in fluoroform, CHF3. ( Full Answer )

How does a hydrogen bond compare to a covalent bond?

The short answer, without too much research or effort on my part, is that hydrogen bonds are weaker. The are due to the attraction of hydrogen to other elements (such as oxygen) that have lone pairs swimming around. Covalent bonds are due to electronic effects, and as such are stronger.

What are hydrogen bonds?

Hydrogen bonds are the bonds that are formed due interaction of a hydrogen atom with an electronegative atom (like oxygen). In these interactions, a hydrogen atom (consisted of only one proton and one electron) is a donor, and the respective electronegative atom is an acceptor of the bond.

Why is a hydrogen bond not a true bond?

Hydrogen bond is not a true bond because in it no bonding takes place i.e. overlapping of orbitals takes place(no sigma or pie bond formation). It is just a weak interaction between hydrogen and a highly electronegative adjacent atom. This atom could be Fluorine, Oxygen or nitrogen. Only these three ( Full Answer )

Is a hydrogen bond a true chemical bond?

No. A hydrogen bond is actually a type of intramolecular force. This means that when a H atom is bonded to the end of a Fluorine (F), Oxygen (O), or Nitrogen (N), it can attach to another F, O, or N to a create what we call in chemistry, a Hydrogen bond.

Why is hydrogen bonding not a true bond?

Hydrogen bonds can be intermolecular (between molecules) or intramolecular (between the atoms of a molecule). Presuming you are asking about the intermolecular 'bonds', they are not actual bonds but are instead a weak attractive force between two molecules which have a hydrogen atom bonded to a ve ( Full Answer )

What is the hydrogen Bonding?

Hydrogen bonding is a strong dipole-dipole attraction that forms between molecules in which hydrogen is bonded to one of the electronegative elements nitrogen, oxygen and fluorine. (dipole-dipole bonds are bonds between dipoles - a molecule that has two oppositely charged poles or ends)

What type of bond is a hydrogen bond?

A hydrogen bond is an intermolecular force. They are the strongest between the three intermolecular forces. These molecules are very polar because they usually occur between VERY ELECTRONEGATIVE atoms such as nitrogen, oxygen and fluorine. eg's- H20, NH3, Hf

How is hydrogen bond different from a covalent bond?

Hydrogen bonds are electrostatic attractions between a hydrogen atom, bonded to a more electronegative atom of one molecule AND a more electronegative atom of another molecule, but there is no sharing of electrons. In covalent bonding, atoms share electrons to form molecules.

Why are hydrogen bonds weak bonds?

Hydrogen bonds are not weak bonds, in fact, they're the strongest. This is because the p orbitals overlap which makes the electrons delocalised. This means that the molecule is more stable and is less likely to break apart to react with anything else.

An example of a hydrogen bond is the bond between?

A common example of hydrogen bonding is the one between water molecules. Hydrogen bonding is an intermolecular type of bonding, so it occurs when the hydrogen of one molecule is attracted to the lone pairs of either Oxygen, Nitrogen or Fluorine because of their high electronegativity. Since water h ( Full Answer )

Hydrogen bonding in water is it a covalent bond or ionic bond?

It is a weak electrostatic attraction between the oxygen atom of one water molecule and a hydrogen atom of another water molecule. There is no sharing or transfer of electrons between the molecules. There are the hydrogen - o ( Full Answer )

Is hydrogen bond a true chemical bond?

Not really, it's more of a particularly strong intermolecular electrostatic interaction than a true bond.\n. \nHydrogen bond strengths are on the order of a few kcal/mol, less than a tenth of even a weak covalent bond.

What type of bond is hydrogen to hydrogen?

Non-polar, single and covalent Bond A bond between two non-metals is generally going to be a covalent bond due to the affinity to electrons and the need to "pick them up." Molecular hydrogen is a good example and the hydrogens are indeed bonded by a covalent bond, sharing electrons to complete a f ( Full Answer )

Which bond is stronger an ionic bond or a hydrogen bond?

Ionic bonds are far stronger than hydrogen bonds. Ice is held together by hydrogen bonds, and table salt, which is sodium chloride (NaCl), is held together by ionic bonds. You can hammer on ice and break the hydrogen bonds holding it together with relative ease. But you can hammer all day on salt, t ( Full Answer )

Why hydrogen chloride does not form hydrogen bond?

According to the definition, to form a hydrogen bond, a bond with hydrogen and another element should have a higher value for electronegativity such as H-N, H-O and H-F. H-Cl does not meet with sufficient polarity to form a hydrogen bond.

Which is stronger a peptide bond or a hydrogen bond?

Peptide bond is a covalent bond. Covalent bonds are stronger than hydrogen bonds. Think of electrons as the glue of a molecule. A covalent bond has electron interaction uniformity(They're glue is pretty consistent between two atoms). Now hydrogen bonds don't have as much glue; think of it as a few ( Full Answer )
