Hydrogen bonds are formed between compounds containing a hydrogen atom covalently bonded to a very electronegative element. The only elements that are electronegative enough are fluorine, oxygen and nitrogen. The extreme difference in electronegativity causes the covalent bond between the atoms to polarize by attracting the centre of electron density towards the Hydrogen atom. This creates positive and negative ends of the compound.
When the positive end of the compound (the Hydrogen atom) comes into contact with the negative end (the other element) of another compound (please note that the other compound must be the same compound or be capable of forming hydrogen bonds) it will form a temporary bond due to the differences in polarity (sign). This temporary bond is a hydrogen bond.
Examples for compounds capable of forming hydrogen bonds are water (H2O), hydrogenflouride (HF) and the base pairs found in DNA.
Chlorine cannot form a hydrogen bond only Nitrogen, Oxygen, and Flourine can
No, hydrogen bonds are not an example of adhesion. Hydrogen bonds are a type of chemical bond that forms between a slightly positive hydrogen atom and a slightly negative atom of another molecule. Adhesion refers to the attraction between different molecules.
Hydrogen bonds with hydrogen bond acceptor atoms such as Oxygen. Covalent bonds with nearly anything.
C4H10 is organic because it contains carbon-hydrogen (C-H) bonds. Organic compounds are typically characterized by the presence of carbon atoms bonded to other atoms like hydrogen, oxygen, nitrogen, etc.
Hydrogen is an element. Oxygen is an element. Hydrogen reacts with Oxygen to form a compound which is called water and has the formula H2O. Hydrogen and Oxygen can also form another compound called Hydrogen peroxide (H2O2)
Slnium forms the compund H2Se, (so behaves like O and S in formation of a hydrogen compound.
Hydrogen typically forms one bond in a chemical compound.
Guanine-cytosine forms three hydrogen bonds, while adenine-thymine forms two hydrogen bonds. Therefore, guanine-cytosine forms more hydrogen bonds.
Hydrogen is an element, not a bond. It can form bonds, which are usually covalent, but an ionic bond with hydrogen is possible, for example, lithium hydride is an ionic compound. While this, like every compound, does have its own distinctive features, I would not call it a special form of ionic bond.
BeH2 is a covalent compound because beryllium typically forms covalent bonds with hydrogen. HCl is considered an ionic compound because hydrogen chloride typically forms an ionic bond between the hydrogen and chlorine ions.
yes it can when it dissolves in water in forms hydrogen bonds in fact its the one that has the most hydrogen bonds
hydrogen and oxygen forms a water compound H2O
Arsenic typically forms three covalent bonds with hydrogen.
Cytosine can hydrogen bond to guanine. In DNA, cytosine forms three hydrogen bonds with guanine, while in RNA, it forms two hydrogen bonds with guanine. These hydrogen bonds help stabilize the DNA double helix structure.
HCl (Hydrogen Chloride) is a covalent compound and forms a covalent bond. However, if water is added to hydrogen chloride, it forms hydrochloric acid which is an ionic compound that has ionic bonds.
Water is composed of molecular bonds, but forms hydrogen bonds with other water molecules. Hydrogen bonds are not actual bonds, but they cause an attraction between the water molecules, which is why water is adhesive.
Oxygen typically forms two bonds with hydrogen to create water (H2O).
