Because hydrogen atoms give up their electrons relatively easily, when they are in a covalent bond they have a fairly positive charge (because its electron spends most of its time around the atom the hydrogen is bonded to).
If there is another molecule that has an area of partially negative charge then the hydrogen will be attracted to it. This bond that forms is not as strong as something like a covalent bond but, it is stronger than van der walls interactions.
A hydrogen bond forms when a hydrogen atom that is covalently bonded to a highly electronegative atom (such as nitrogen, oxygen, or fluorine) is attracted to another electronegative atom in a different molecule. This creates a weak electrostatic attraction between the hydrogen atom and the electronegative atom.
When the atom hydrogen bonds directly to a small atom with a high electronegativity such as nitrogen, oxygen and fluorine. The Hydrogen atom then has a slightly positive charge and the other atom a slightly negative charge. This causes forces of attraction between molecules which is known as hydrogen bonding.
Hydrogen bonding is characterized by the interaction between compounds that are made up of hydrogen atoms and atom(s) which are highly electronegative. Such atoms include nitrogen, fluorine and oxygen.
The highly electronegative atom will attract the shared electrons in the covalent bond and pull it towards its nucleus. This forms a slight positive charge at the hydrogen atom and a slight negative charge at the highly electronegative atom.
The difference in charges will then act on the molecules, which causes them to form intermolecular forces.
A hydrogen bond occurs when two electronegative (Electronegative is a chemical property that describes the power of an atom (or, more rarely, a functional group) to attract electrons towards itself )atoms, such as nitrogen and oxygen, interact with the same hydrogen.
The hydrogen is normally covalently (Covalent bonding is a form of chemical bonding that is characterized by the sharing of pairs of electrons between atoms, or between atoms and other covalent bonds) attached to one atom, the donor, but interacts electrostatic ally with the other, the acceptor. This interaction is due to the dipole ( An electric dipole is a separation of positive and negative charge. The simplest example of this is a pair of electric charges of equal magnitude but opposite sign, separated by some, usually small, distance) between the electronegative atoms and the proton.
Hydrogen is one of the least electronegative elements that readily form covalent bonds. Therefore, in most covalent bonds between hydrogen and any other atom, the hydrogen end of the bond has a net positive electrical polarity, because the electrons from hydrogen and the other element have a higher probability of being found nearer to the other atom than to the hydrogen atom. Also, hydrogen has the smallest of all nuclei, so that when no electron is near it, it temporarily has a strong attraction for electrons from other sources. The hydrogen end of a polar covalent bond is therefore attractive to the paired valence electrons in the outer electron shells of highly electronegative atoms, such as fluorine and oxygen, that are covalently bonded. As a result, the attraction between the hydrogen end of a covalent bond and the electrons in the outer shells of other covalently bonded atoms keeps the average distance between (i) the nucleus of the hydrogen atom in the hydrogen end of a covalent bond and (ii) the nucleus of another covalently bonded atom in another molecule smaller on average than the distance between any other kinds of nuclei that are not directly bonded to one another in a molecule. Because of this, the intermolecular attraction between molecules of compounds that contain a covalently bonded hydrogen is greater than any other kind of intermolecular attraction in covalent compounds, and the difference is great enough that it has been agreed to call this phenomenon a "hydrogen bond", even though it is weaker than almost any other kind of chemical bond.
a hydrogen bond is formed when a charged part of a molecule having polar covalent bonds forms an electrostatic interaction with a substance of opposite charge.
it forms covalent bonds. A hydrogen ion shares one electron from its outermost shell with another hydrogen ion. As such, there are 2 electrons being shared in a hydrogen molecule.
Hydrogen bonds form of a hydrogen is bonded to either an oxygen, a nitrogen or a fluorine.

Does vanillin hydrogen bond?
Yes, vanillin can hydrogen bond. Vanillin contains oxygen atoms that can serve as hydrogen bond acceptors, allowing it to form hydrogen bonds with hydrogen atoms from other molecules.
Does CH3NH2 form a hydrogen bond?
Yes, CH3NH2 can form hydrogen bonds. The nitrogen in CH3NH2 is capable of acting as a hydrogen bond acceptor, while the hydrogen atoms attached to nitrogen can act as hydrogen bond donors.
Why chlorine is not included to make hydrogen bond?
Chlorine does not form hydrogen bonds because it lacks hydrogen atoms that are necessary to establish these bonds. Hydrogen bonds occur between hydrogen atoms and electronegative atoms like oxygen, nitrogen, or fluorine. Chlorine is not electronegative enough to participate in hydrogen bond formation.
What type of bond is hydrogen?
Hydrogen forms a covalent bond with other elements, meaning it shares electrons with another atom to complete its outer shell.
What is formed when you bond hydrogen and chlorine?
When hydrogen and chlorine bond, they form hydrogen chloride (HCl), a highly corrosive and reactive gas. The bond between hydrogen and chlorine is a covalent bond, where both atoms share electrons to achieve stability.
What type of bond will carbon form with hydrogen?
Hydrogen form a covalent bond with carbon.
Can hydrogen and oxygen form an ionic bond?
No, hydrogen and oxygen do not form an ionic bond. They typically form a covalent bond when they combine to make water (H2O). In this bond, they share electrons instead of transferring them.
How bonds does hydrogen have?
Hydrogen can form one bond.
Is a hydrogen bond stronger than a covelant bond?
No. A hydrogen bond isn't even an actual bond. It is a form of intermolecular attraction.
Is oxygen and hydrogen a ionic bond?
No, oxygen and hydrogen do not form an ionic bond. When oxygen and hydrogen bond to form water, they share electrons in a covalent bond, where electrons are shared between the atoms rather than transferred.
What do hydrogen ions bond with to form acids in solution?
covalent bond
Do hydrogen and oxygen create an ionic bond?
No. They form a covalent bond.
Does hf form hydrogen bond?
Yes, it can.
Does vanillin hydrogen bond?
Yes, vanillin can hydrogen bond. Vanillin contains oxygen atoms that can serve as hydrogen bond acceptors, allowing it to form hydrogen bonds with hydrogen atoms from other molecules.
How do bonds form between water molecules?
The bond between water molecules is known as a hydrogen bond.
What is formed when you bond hydrogen and fluorine?
When hydrogen and fluorine bond, they form hydrogen fluoride (HF), a colorless gas at room temperature that dissolves easily in water to form a strong acid. The bond between hydrogen and fluorine is a polar covalent bond, with fluorine attracting the electrons more strongly than hydrogen.
Does CH3NH2 form a hydrogen bond?
Yes, CH3NH2 can form hydrogen bonds. The nitrogen in CH3NH2 is capable of acting as a hydrogen bond acceptor, while the hydrogen atoms attached to nitrogen can act as hydrogen bond donors.
