what is hydrogen bonding? Explain it in terms of Hydrogen Fluoride.
Answers
The hydrogen bond is an interaction involving a hydrogen atom located between a pair of other atoms having a high affinity for electrons such as nitrogen, oxygen or fluorine. It is an electrostatic attraction between two polar groups. This occurs when a hydrogen atom (H) is bound to a highly electronegative atom such as nitrogen (N), oxygen (O), or fluorine (F), and experiences the electrostatic field of another highly electronegative atom nearby.
In terms of Hydrogen Fluoride
Hydrogen fluoride is a chemical compound with the chemical formula HF. This colorless gas or liquid is the principal industrial source of fluorine, often as an aqueous solution called hydrofluoric acid. It is an important feedstock in the preparation of many important compounds including pharmaceuticals and polymers (e.g. Teflon). HF is widely used in the petrochemical industry as a component of superacids. Hydrogen fluoride boils near room temperature, much higher than other hydrogen halides.
Hydrogen bonding is an electrostatic force between covalent molecules with hydrogen and an electronegative element & sp hybrid carbon.
H bonding doesn't take place in ionic compounds
Hydrogen bond is weaker but is stronger than van der waals force.
There is dipole- dipole interactions.
Hydrogen bond forms in polar covalent compounds.
