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.
When polar molecules (like water or salt) attract to other polar molecules this type of bond holds them together?
When polar molecules, such as water or salt, attract to other polar molecules, the type of bond that holds them together is called a hydrogen bond. This occurs due to the partial positive charge of hydrogen atoms in one molecule being attracted to the partial negative charge of electronegative atoms (like oxygen) in another. These interactions are weaker than covalent bonds but play a crucial role in the physical properties of substances, such as the high boiling point of water.
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 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.
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.
Which type of bond forms between oppositely-charged region of polar molecules?
Hydrogen bond
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
