proton bond
Its a weaker bond than covalent or ionic bonding. Its call Hydrogen Bonding. Do to the configuration of H20 positive and negative charges occur on the molecule. So specific areas such as the oxygen(w/ a slight negative charge) will attract to a hydrogen(w/ a slight positive charge) on a different H20 molecule. You can observer this phenomenon by observing that water has a surface tension.
Hydrogen bonds. They are weak individually, but enough of them have some strength ( water, for instance ) through the are not strong enough to impede the splitting of the DNA molecule when a replicative process, for instance, needs preforming.
A water (H2O) molecule is held together by covalent bonds. Since oxygen has a higer electronegativity than hydrogen, the bonding electron pairs tend towards the oxygen atom, making the oxygen atom a slight negative pole and the hydrogen atoms positive poles. With the additional V shape of the molecule that comes from oxygen's free electron pairs, the slightly polar bonds make the molecule a dipole with the negative pole on oxygen's side and the positive pole in the center between the hydrogen atoms. (This polarity is why a stream of water can be manipulated with a magnet.) The H2O molecule does not conduct electricity as there are no delocalised electrons.
There are multiple processes which can result in the formation of a water molecule. One example is the neutralization of an acid and a base which forms salt and water (e.g. HCl + NaOH ---> H2O +NaCl). In those types of reactions a water molecule is formed when a proton (aka an H+ cation) bonds with a hydroxide anion. There are several other water forming reactions. Another would be the dehydration synthesis of two monosaccharides.
Yes Yes
Water is a polar molecule forming many intermolecular hydrogen bonds.
hydrophilic
They are all molecules capable of forming hydrogen bonds.
Because glucose has many -OH groups, which are capable of forming hydrogen bonds with water molecules.
There are two covalent bonds present in a water molecule.
Within a water molecule is covalent bonds. between water molecules are hydrogen bonds.
Adjacent water molecules are connected by the electrical attraction between the oxygen of one water molecule and the hydrogen of another water molecule. This type of bonding is called hydrogen bonding.
Two water molecules can react to from hydrogen bonds. If one water molecule acts as an acid and donates a proton to another water molecule then hydronium ions an hydroxyl ions can be formed as well.
The water molecule is H2O; the intermolecular bonds are hydrogen bonds.
One molecule of water (H-O-H) contains two ionic bonds.
Each water molecule forms multiple hydrogen bonds with neighboring water molecules. These bonds are transient and easily and quickly shift among molecules.
