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.
This is a type of polar interaction when hydrogenâs slightly positive charge attracts the negative charge of another molecule. This has to do with dipole moments, and is discussed further in chemistry (so read that shit if you want some brain pain). This is essential for life (water, proteins, DNA, etc).
