Quick Answer: What Best Describes A Hydrogen Bond?

Which is the best description of hydrogen bonding?

The best description of hydrogen bonding is the association between a hydrogen atom which is somewhat positive because it is bonded to a small electronegative atom and an atom of O, N or F on another molecule..

Is water a hydrogen bond?

Water. A ubiquitous example of a hydrogen bond is found between water molecules. In a discrete water molecule, there are two hydrogen atoms and one oxygen atom. … Liquid water’s high boiling point is due to the high number of hydrogen bonds each molecule can form, relative to its low molecular mass.

Is a hydrogen bond stronger than a covalent bond?

A hydrogen bond is not stronger than a covalent bond. Intramolecular bonds such as covalent bonds are always stronger than intermolecular bonds.

What is the weakest bond in chemistry?

ionic bondThe ionic bond is generally the weakest of the true chemical bonds that bind atoms to atoms.

How does a hydrogen bond work?

Hydrogen Bonding. Hydrogen bonding is a special type of dipole-dipole attraction between molecules, not a covalent bond to a hydrogen atom. It results from the attractive force between a hydrogen atom covalently bonded to a very electronegative atom such as a N, O, or F atom and another very electronegative atom.

What is hydrogen bond explain with example?

hydrogen bond. noun. The definition of hydrogen bond is a chemical bond between the hydrogen atom and an electronegative atom. An example of hydrogen bond is water molecules bonding together in the form of ice.

What describes a hydrogen bond?

A hydrogen bond is the electromagnetic attraction created between a partially positively charged hydrogen atom attached to a highly electronegative atom and another nearby electronegative atom. A hydrogen bond is a type of dipole-dipole interaction; it is not a true chemical bond.

Why is a hydrogen bond so strong?

Hydrogen bonds are strong intermolecular forces created when a hydrogen atom bonded to an electronegative atom approaches a nearby electronegative atom. Greater electronegativity of the hydrogen bond acceptor will lead to an increase in hydrogen-bond strength.

What is a hydrogen bond easy definition?

noun. a weak chemical bond between an electronegative atom, such as fluorine, oxygen, or nitrogen, and a hydrogen atom bound to another electronegative atom. Hydrogen bonds are responsible for the properties of water and many biological molecules.

Which bond is the strongest?

Covalent bondAnswer: Covalent bond is the strongest bond. Answer: There are a variety of ways atoms bond to one another.

What is the difference between a covalent bond and a hydrogen bond?

Covalent bonds are intramolecular bonds whereas hydrogen bonds are intermolecular bonds. Water is held together with covalent bonds. In covalent bonds, electrons are shared between the atoms. … Due to these partial charges, the hydrogen is also attracted to the oxygen atom of a second water molecule.

When can a hydrogen bond form?

Intramolecular hydrogen bonds This occurs when two functional groups of a molecule can form hydrogen bonds with each other. In order for this to happen, both a hydrogen donor a hydrogen acceptor must be present within one molecule, and they must be within close proximity of each other in the molecule.

What bonds are hard to break?

while the other bonds have enthalpies lower than the c-c bond but higher than the c-n and c-co bonds…..which makes c-s bond most easy to break and the c-c most difficult to break.

Which hydrogen bonding is the strongest?

HFThe hydrogen bond in HF is strongest, because fluorine is the most electronegative element.
