The Vietnam War (1954-1973) was a very long and costly war in which over three million people lost their lives. The United States became involved in the war to support their allies in South Vietnam. The U.S. and South Vietnam were fighting against the communist regime known as the Viet Kong.
Ion-dipole interaction (dipole-ion interaction): A noncovalent attraction between one pole of a bond dipole and an oppositely-charged ion. The Î´+ end of the bond dipole is attracted to an anion, and the Î´- end of the bond dipole is attracted to a cation.
The induced dipole forces appear from the induction (also known as polarization), which is the attractive interaction between a permanent multipole on one molecule with an induced (by the former di/multi-pole) multipole on another. This interaction is called the Debye force, named after Peter J.W. Debye.
