Answer:
Cl₂ < CH₃Cl < CH₃COOH < NaCl
Explanation:
<em>Part A. List the substances NaCl, Cl₂, CH₃Cl, and CH₃COOH in order of increasing strength of intermolecular attractions.</em>
<em />
NaCl. Na⁺ is bonded to Cl⁻ through a ionic bonding. In the crystalline reticle, unit formulas attract each other through ion-ion forces, which are the strongest type of forces.
Acetic acid (CH₃COOH) has H atoms bonded to more electronegative O atoms. This leads to the formation of hydrogen bondings, which constitute an especially strong case of dipole-dipole forces.
Chloromethane (CH₃Cl) is a polar molecule due to the asymmetrical distribution of charge density. The resulting intermolecular attractions are dipole-dipole forces.
Cl₂ is nonpolar and it has the weakest type of intermolecular attractions, dispersion forces.
The order of increasing strength is Cl₂ < CH₃Cl < CH₃COOH < NaCl
