what is the difference between the political interaction and hydrogen bonding
Answers
Answer:
Hydrogen bonding is a special case of dipole-dipole interactions. Both strong and weak hydrogen bonds can form but when people talk about hydrogen bonding they usually mean strong hydrogen bonds, which result in systems with hydrogen atoms bonded to very electronegative atoms (oxygen, nitrogen, fluorine...). Hydrogen bonds are given their own category because the are relatively strong compared to other non-covalent interactions.
There isn't really anything special about the dipole that makes them strong, it's because the electronegative atom will pull electron density away from the hydrogen and leave an almost completely de-shielded proton. The hydrogen atom can then get much closer to the electronegative atom of another molecule than would normally be possible because of the reduced pauli repulsion. Since electrostatic attraction gets stronger as charges get closer, the interaction is noticeably stronger than the average dipole-dipole interaction.
