**Boiling Point and Intermolecular Forces**Boiling point is directly related to the strength of the intermolecular forces between each molecule. In a liquid sample of n-butanol, there are three different intermolecular forces present:1. **Hydrogen Bonding**: This is a strong intermolecular force that occurs when a hydrogen atom, covalently bonded to a highly electronegative atom like oxygen, interacts with another electronegative atom. In n-butanol, hydrogen bonds form between the hydrogen of the hydroxyl group (-OH) and the oxygen of neighboring molecules.2. **Dipole-Dipole Interactions**: These occur between molecules that have permanent dipoles. The polar nature of the n-butanol molecule leads to dipole-dipole interactions, contributing to its overall intermolecular forces.3. **London Dispersion Forces**: These are weaker forces present in all molecules, arising from temporary dipoles as electrons move around the nucleus. They are the only type of forces acting between nonpolar molecules.Among these, **hydrogen bonding** is the strongest intermolecular force present in n-butanol, significantly influencing its boiling point.

The structural formula of n-butanol is CH3-CH2-CH2-CH2-O-H.

Two liquids – one polar, one nonpolar – have the same molar mass. Which one has the higher boiling point? A. The polar liquid will have the higher boiling point, since its molecules have dipole-dipole interactions. B. They will have similar boiling points, since the dispersion forces depend upon molar mass. C. The nonpolar liquid will have the higher boiling point, since its molecules are more loosely held together. D. The nonpolar liquid will have the higher boiling point, since the polar molecules will repel each other and lower the boiling point. E. It is impossible to say without additional information.
