Do all chemical bonds shed a single water molecule?

Obviously not all chemical bonds, but only a few specific chemical bonds can strip a water molecule. For example, amino acid molecules form amide bonds by losing water in pairs; Alcohol is dehydrated intramoleculeally to form olefins, alcohol is dehydrated between molecules to form ethers, and so on.

But these can only be specific chemical bonds, usually with groups such as hydroxyl (-OH) groups. Sodium chloride, sodium carbonate, iron sulfate and other molecules cannot remove a water molecule.

At the same time, it should be pointed out that there is a common sense mistake in your question: the nucleotide chain is not formed by the loss of "one water molecule" by the nucleotide, here two single nucleotide molecules and one molecule of phosphoric acid lose [two molecules] of water to form an ester bond, which is a 3,5-phosphodiester bond.

The main dehydration reactions are:

Acid-base neutralization reaction, water molecules are removed. Or rather, water is produced. In fact, it's not called dehydration.

Intermolecular dehydration: glycol ether formation (2ch3ch2oh ch3ch2och2ch3 + h2o, concentrated sulfuric acid, 140).

Acid alcohol esterification (CH3COOH + CH3CH2OH CH3COOCH2CH3 + H2O, concentrated sulfuric acid, water bath, reversible).

Amino acid dehydration condensation (glycine 2NH2CH2COOH NH2CH2CONHCH2COOH + H2O, enzyme catalysis).

Dehydration condensation of other molecules (e.g., dehydration condensation of salicylic acid).

Intramolecular dehydration (elimination): alcohol dehydration (CH3CH2OH C2H4 + H2O, concentrated sulfuric acid, 170).

Dehydration and carbonization of organic matter: such as sucrose, ethanol, etc.

Acid-base neutralization reaction, water molecules are removed. Or rather, water is produced. In fact, it's not called dehydration. It is the ionic bond that is formed.

In addition, there are three main types of intramolecular bonds: covalent bonds (coordination bonds are also special covalent bonds), ionic bonds, and metallic bonds. There are a lot of dehydration reactions in covalent bonds.

What you understand should be in the range of covalent bonds.

In addition to hydrogen bonding, there are also intermolecular forces between water molecules, also known as van der Waals forces, which include orientation forces, induction forces, and dispersion forces, and the water molecules you are talking about are polar molecules, so all three forces exist.

There are only dispersion forces between non-polar molecules, dispersion and induction forces between non-polar and polar forces, and all three forces between polarity and polarity. Water, with the chemical formula HO, is an inorganic substance composed of two elements, hydrogen and oxygen, which is non-toxic and drinkable.

It is a colorless and odorless transparent liquid at room temperature and pressure, and is known as the source of human life. Water is one of the most common substances on Earth. 72% of the Earth's surface is covered by water.

It is an important resource for the survival of all life, including inorganic chemistry and human beings, and it is also the most important component of living organisms.

Because the mutual attraction between dipoles involves hydrogen atoms, it is called hydrogen bonding (hydrogen bonding indicates the mutual attraction between polar molecules containing hydrogen. Hydrogen bonds are weaker than the covalent bonds between oxygen and hydrogen atoms in water molecules). The water molecule is held together by strong hydrogen bonds due to its distinct water molecule dipole appendage.

They tend to stick together firmly, so there should be intermolecular forces as well.

Covalent bonds, ionic bonds, metal parts... Give it satisfaction!

First, both electrolytes and non-electrolytes must be compounds. Among them, electrolyte refers to the compound that can ionize freely moving anions and cations in an aqueous solution or in a molten state. Sulfur dioxide and ammonia are non-electrolytes, but chlorine and bromine are elemental and are neither electrolytes nor non-electrolytes.

The water molecule is bound internally by O-H covalent bonds, and it takes a high energy to break it.

Water molecules are inter-molecular hydrogen bonds....h, less energy is required to break hydrogen bonds.

The reaction can be calculated theoretically whether it can occur or not, i.e., the Gibbs free energy 0 cannot be carried out, but it is still necessary to explain the problem according to the experimental facts.

The elements of hydrogen and oxygen in the water molecule are combined in the form of chemical bonds and hydrogen bonds. Hydrogen bonds are not chemical bonds.

Chemical bonds include: ionic bonds.

Covalent bond. Metallic bonds.

It is excites to exist separately.

Ionic compounds.

Covalent compounds.

Metal monotonous hosiery hosiery.

Middle. NaCl (most salts, except aluminium chloride.

All are ionic compounds.

HCl (most non-metallic compounds and aluminum chloride) are covalent compounds.

Chemical bonds exist between atoms and between molecules.

Present between molecules (e.g. carbon dioxide.

Between molecules, chlorine.

There are only two kinds of forces between molecules

Intermolecular forces. And. Hydrogen bond.

The common ones are: intermolecular forces: halogen elemental gases (chlorochlorobromoiodine) hydrogen bonds: water. Ammonia molecule.

It is to be clear that there are intermolecular forces between water molecules and there are no chemical bonds.

Intermolecular forces are not chemical bonds.

Intermolecular forces include van der Waals forces and hydrogen bonding.

There are van der Waals forces between water molecules, and there are also hydrogen bonds, because the action of hydrogen bonds is greater than van der Waals forces, so the main factor affecting the physical properties of water is hydrogen bonds.

This is not true.

There are two H—O bonds (hydrogen bonds) in each water molecule, and there are no H—H bonds, which is the problem.

Hydrogen bonding between water molecules is an intermolecular force and is not a chemical bond. It is not a range that should be considered in the molecule and should not be an interference. Therefore, it is wrong to say that there are chemical bonds between atoms in a water molecule.

Hope it helps.

A water molecule is structured with the formula .

There are covalent bonds between H and O in each water molecule of H-O-H, and there are hydrogen bonds and intermolecular forces between adjacent water molecules, but the intermolecular forces are weaker than hydrogen bonds.

No, it is only between adjacent H-O, and there is no chemical bond between H and H.

Hydrogen bonding is not a chemical bond, it is an intermolecular force, and you must pay attention to this knowledge, which is the most error-prone.
