Question

question 2 (2 points)
indicate the strongest attraction between the two molecules
1 between two nonpolar molecules
2 between a nonpolar molecule and a polar molecule
3 between a nonpolar molecule and an ion
4 between two polar molecules
5 between a polar molecule and an ion
6 between two polar molecules where one has an n and the other has an o - h
a. londons b. dipolar c. hydrogen bond d. ion - dipole

Explanation:

• 1. Between two non - polar molecules: London's forces (also known as dispersion forces) are the only intermolecular forces acting between non - polar molecules. These forces arise due to temporary dipoles formed by the movement of electrons in the molecules.
• 2. Between a non - polar molecule and a polar molecule: Dipole - induced dipole forces. The polar molecule has a permanent dipole, which can induce a dipole in the non - polar molecule.
• 3. Between a non - polar molecule and an ion: Ion - induced dipole forces. The ion's charge can induce a dipole in the non - polar molecule.
• 4. Between two polar molecules: Dipolar forces (dipole - dipole forces). The permanent dipoles of the polar molecules attract each other.
• 5. Between a polar molecule and an ion: Ion - dipole forces. The ion is attracted to the oppositely charged end of the polar molecule's dipole.
• 6. Between two polar molecules where one has an N and the other has an O - H: Hydrogen bond. A hydrogen bond is a special type of dipole - dipole interaction where a hydrogen atom (bonded to a highly electronegative atom like O or N) is attracted to another electronegative atom (like N or O).

4. B. dipolar (dipole - dipole)
5. D. ion - dipole
6. C. hydrogen bond
