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

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 hydro

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 o

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 fluo

Is hydrogen-hydrogen a polar bond?

No , basically because two atoms of the same element will have the same electronegativities as each other , therefore they are non-polar as they have an EQUAL distribution of

Is carbon and hydrogen a hydrogen bond?

No, it is not, it is a co-valent bond. hydrogen bond is much weaker (5-30kJ/mol) to form a stable compound like methane or mostly all of the hydrocarbons with the carbon hydro

What is a hydrogen bond and why is that important for water?

Hydrogen bonds are what give water its amazing abilities ofcohesion, adhesion, and surface tension. Cohesion is what makeswater molecules stick together. Think about watching
