Question #91972
What is hydrogen bonding
Expert's answer

A hydrogen bond is a weak type of force that forms a special type of dipole-dipole attraction which occurs when a hydrogen atom bonded to a strongly electronegative atom (usually O, N or F) exists in the vicinity of another electronegative atom (usually O, N or F) with a lone pair of electrons. These bonds are generally stronger than ordinary dipole-dipole and dispersion forces, but weaker than true covalent and ionic bonds.

Hydrogen bonding influences physical properties of substances such as temperature of boiling. The substance with hydrogen bonding will have higher temperature of boiling among the alike substances:

for example:

H2O 100 C

H2S -60C

HeSe -40 C

H2Te 0 C
