Quantum characteristics of the hydrogen bond
WebApr 1, 2024 · A hydrogen bond is unusual and often called an electrostatic dipole-dipole interaction (a weak intermolecular interaction), lumping it in with more transient bonds caused by momentary quantum fluctuations in electric charge, but it also has many characteristics of the much stronger covalent bonds, where electron clouds actually … WebApr 9, 2024 · Some examples of hydrogen bonding are as follows. 1. Water. A water molecule is composed of a highly electronegative oxygen atom linked to the hydrogen atom. The electrons of the shared pair are attracted more by the oxygen atom, and this end of the molecule becomes negative, and the hydrogen atoms become positive.
