Which of the following molecules will bond to like molecules by dispersion forces only?*1 pointHF, HCl, HBrF₂, CO₂, CH₃NH3, HF, CH₃OHC₂H4, C₂H₅OH, CH₃COOH

The molecule that will bond to like molecules by dispersion forces only is F₂. Here's why:

1. Dispersion forces, also known as London dispersion forces, are the weakest type of intermolecular force. They occur between all molecules, whether polar or nonpolar.

2. HF, HCl, and HBr are all polar molecules due to the difference in electronegativity between hydrogen and the halogens. Therefore, they will experience dipole-dipole interactions in addition to dispersion forces.

3. CO₂ is a nonpolar molecule, but it's linear shape allows it to have dipole-induced dipole interactions.

4. CH₃NH2, HF, and CH₃OH are all capable of hydrogen bonding due to the presence of a hydrogen atom bonded to a highly electronegative atom (N, O, or F). Therefore, they will experience hydrogen bonding in addition to dispersion forces.

5. C₂H4, C₂H₅OH, and CH₃COOH are also capable of hydrogen bonding due to the presence of a hydrogen atom bonded to a highly electronegative atom (O). Therefore, they will experience hydrogen bonding in addition to dispersion forces.

6. F₂, however, is a nonpolar molecule and does not have any hydrogen atoms bonded to highly electronegative atoms. Therefore, it will experience only dispersion forces when bonding to like molecules.
