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.
As the polarity of the covalent bond increases, so will the dipole-dipole forces. Hydrogen bonding. is a special kind of dipole-dipole attraction that occurs with a hydrogen atom covalently bonded to N, O, or F. H-bonding between molecules is the strongest kind of dipole-dipole attraction.s the polarity of the covalent bond increases, so will the dipole-dipole forces.
