Question

define hydrogen bonding.Explain how the forces affect the physical properties of compounds.​

Answer 1

Answer:

Hydrogen bonding is a special type of dipole-dipole attraction between molecules, not a covalent bond to a hydrogen atom. It results from the attractive force between a hydrogen atom covalently bonded to a very electronegative atom such as a N, O, or F atom and another very electronegative atom.

Explanation:

Intermolecular forces are the forces that bind two molecules together. Physical properties are affected by the strength of intermolecular forces. Melting, boiling, and freezing points increase as intermolecular forces increase. Vapor pressure decreases as intermolecular forces increase.

Answer 2

$\huge\fbox\red{❥answer}$

Hydrogen bonding, interaction involving a hydrogen atom located between a pair of other atoms having a high affinity for electrons; such a bond is weaker than an ionic bond or covalent bond but stronger than van der Waals forces.

Hydrogen bonding, interaction involving a hydrogen atom located between a pair of other atoms having a high affinity for electrons; such a bond is weaker than an ionic bond or covalent bond but stronger than van der Waals forces. Stronger intermolecular forces will also result in a higher physical properties such as higher melting or boiling points, which require breaking molecules apart. Since a higher vapor pressure means that it's easier to vaporize a compound, this means that lower intermolecular forces leads to a higher vapor pressure.
