Is it true that hydrogen bond is a weak chemical attraction between polar molecules?
Yes, it is true. A hydrogen bond is a weak attraction between a hydrogen atom in a polar molecule and an electronegative atom in another polar molecule. The strength of a hydrogen bond is weaker than covalent or ionic bonds.
Why oil is not dissolve in water?
oil is non-polar, so cannot form bonds with the water molecules - water molecules are polar, and hydrogen-bond to each other so for a substance to dissolve in water is must also be polar in order to form hydrogen bonds or permanent dipole - permanent dipole bonds.
How do polar molecules differ from non-polar molecules?
Polar molecules have positive charge on one side and negative charge on other side. Non polar molecules have covalent bond and do not have positive and negative charge on one or other side of the molecule.
Which of the following molecules has a polar covalent bond iron oxide (Fe2O3) potassium chloride (KCl) bromine gas (Br2) hydrogen fluoride (HF)?
HF has a polar covalent bond.
What kind of bond is created by a weak electrical between polar molecules?
Dipole-dipole attraction. It isn't really a bond that is formed, but an attraction between opposite charges. The only time polar molecules are attracted via a hydrogen bond (which isn't really a bond either) is if the hydrogen is attached to either a nitrogen (N), oxygen (O) or fluoride (F) atom.
What enables water molecules to hydrogen bond to each other?
the polar nature of the O-H bond
What exists in all polar molecules?
A hydrogen bond
Which bond type is formed between two polar molecules that contain hydrogen?
a hydrogen bond
What is the attraction between the polar regions of molecules?
Hydrogen Bond
Do polar molecules form hydrogen bond when they dissolve in water?
yes
What is a bond between polar covalent molecules called?
A bond between polar covalent molecules is called a hydrogen bond. It is a weak type of bond that forms between a partially positive hydrogen atom and a partially negative atom (such as oxygen or nitrogen) in another molecule.
Which type of bond forms between oppositely-charged region of polar molecules?
Hydrogen bond
What is a relatively weak bond between polar molecules?
A hydrogen bond is a relatively weak bond formed between polar molecules. It occurs between a hydrogen atom bonded to an electronegative atom (such as nitrogen, oxygen, or fluorine) and another electronegative atom in a different molecule.
Is it true that hydrogen bond is a weak chemical attraction between polar molecules?
Yes, it is true. A hydrogen bond is a weak attraction between a hydrogen atom in a polar molecule and an electronegative atom in another polar molecule. The strength of a hydrogen bond is weaker than covalent or ionic bonds.
What is H-bond?
It can either be a polar oovalent bond as in ammonia or could refer to an intermolecular hydrogen bond (between molecules of ammonia.
Are hydrogen bond hydrophobic?
Hydrogen bonds are not hydrophobic. In fact, hydrogen bonds are typically important in stabilizing the structure of many hydrophilic molecules in water by forming between polar molecules or within the same molecule. Hydrophobic interactions, on the other hand, are interactions between non-polar molecules that tend to be repelled by water.
Does a hydrogen bond have a weak chemical attration between polar molecules?
No. Hydrogen bonding is a form of strong intermolecular attraction
