Is there extensive intramolecular hydrogen bonding in the condensed phase of water?
Water can act both as an acid and as a base. There is extensive intramolecular hydrogen bonding in the condensed phase.
Does water have intramolecular hydrogen bonding?
Hydrogen bonds can be intermolecular (occurring between separate molecules) or intramolecular (occurring among parts of the same molecule). This type of bond can occur in inorganic molecules such as water and in organic molecules like DNA and proteins.
Why is the hydrogen bond in water a very weak bond?
Hydrogen bonding of water molecules Thanks to their polarity, water molecules happily attract each other. These attractions are an example of hydrogen bonds, weak interactions that form between a hydrogen with a partial positive charge and a more electronegative atom, such as oxygen.
What is extensive hydrogen bonding?
Mainly through electrostatic attraction, the donor atom effectively shares its hydrogen with the acceptor atom, forming a bond. Because of its extensive hydrogen bonding, water (H2O) is liquid over a far greater range of temperatures that would be expected for a molecule of its size.
Why do hydrogen bonds form between adjacent water molecules?
Hydrogen bonds form between adjacent water molecules because the positive charged hydrogen end of one water molecule attracts the negative charged oxygen end of another water molecule. Water molecules stick to other materials due to its polar nature. This property is called adhesion.
What is the difference between intermolecular and intramolecular hydrogen bonding?
There are two forms of hydrogen bonding as intermolecular and intramolecular hydrogen bonds. The difference between intermolecular and intramolecular hydrogen bonding is that intermolecular hydrogen bonding occurs in between two molecules whereas intramolecular hydrogen bonding occurs in a single molecule.
In which of the following intramolecular hydrogen bond is not present?
Now, we will refer to each chemical compound and we know that in p-nitrophenol, the OH and NO2 are far apart from each other and are not able to form an intramolecular H-bond. So, p-nitrophenol (option D) will not form an intramolecular hydrogen bond.
What is intramolecular hydrogen bonding with example?
Intramolecular hydrogen bonding It is formed when a hydrogen atom is in between the two highly electronegative (F, O, N) atoms present within the same molecule. For example, In o-nitrophenol, a hydrogen atom is present in between the two oxygen atoms.
When hydrogen bonds form between water molecules water evaporates or condenses?
The water molecules in the water absorb that energy individually. Due to this absorption of energy the hydrogen bonds connecting water molecules to one another will break. The molecules are now in the gaseous state; this is called water vapour. The phase change from liquid to vapour is called evaporation.
Why is intramolecular hydrogen bonding?
Intramolecular hydrogen bonds This occurs when two functional groups of a molecule can form hydrogen bonds with each other. In order for this to happen, both a hydrogen donor a hydrogen acceptor must be present within one molecule, and they must be within close proximity of each other in the molecule.
Does hydrogen bonding occur in the condensed phase of water?
B There is extensive intramolecular hydrogen bonding in the condensed phase. Water is neutral. It acts both as a base and as an acid. There is extensive intermolecular hydrogen bonding in the condensed phase. The density of heavy water is more than the density of water, therefore, D2Osinks in normal water.
Intermolecular Hydrogen Bonding: Intermolecular hydrogen bonding occurs between two neighbouring molecules. Intramolecular Hydrogen Bonding: Intramolecular hydrogen bonding occurs within the molecule itself. Intermolecular Hydrogen Bonding: Intermolecular hydrogen bonding has high melting and boiling points, and low vapour pressure.
How is ice formed in the condensed phase?
Ice formed by heavy water sinks in normal water. Water is oxidized to oxygen during photosynthesis. There is extensive intramolecular hydrogen bonding in the condensed phase. Water is neutral. It acts both as a base and as an acid. There is extensive intermolecular hydrogen bonding in the condensed phase.
Which of the following is an example of hydrogen bonding?
Intramolecular Hydrogen Bonding: O-nitrophenol and salicylic acid are examples of intramolecular hydrogen bonding. Compounds with intermolecular hydrogen bonds are more stable than compounds with intramolecular hydrogen bonds.
