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.
In chemistry, dipole moments are applied to the distribution of electrons between two bonded atoms. The existence of a dipole moment is the difference between polar and nonpolar bonds. Molecules with a net dipole moment are polar molecules.ipole moments are a vector quantity. The magnitude is equal to the charge multiplied by the distance between the charges and the direction is from negative charge to positive charge.
