question 13) think about how two fatty acid molecules would interact with each other. what imf could occur between the nonpolar region of one fatty acid with the nonpolar region of another fatty acid? what imf could occur between the polar region of one fatty acid with the polar region of another fatty acid? (6 pts)

Explanation:

• Non - polar regions: London dispersion forces (also known as van der Waals forces or induced dipole - induced dipole forces) occur between non - polar regions. These forces are due to the temporary fluctuations in electron distribution within molecules, creating instantaneous dipoles that induce dipoles in neighboring molecules.
• Polar regions: Hydrogen bonding (if the polar region contains an - OH group, for example) or dipole - dipole interactions (a more general case for polar regions that may not have the specific - OH, - NH₂ etc. groups required for hydrogen bonding). Dipole - dipole interactions occur because polar molecules have a permanent dipole moment (a separation of positive and negative charges within the molecule), and the positive end of one dipole is attracted to the negative end of another dipole. Hydrogen bonding is a special type of dipole - dipole interaction that occurs when a hydrogen atom is bonded to a highly electronegative atom (such as O, N, or F) and interacts with another electronegative atom.

Answer:

• Between non - polar regions: London dispersion forces.
• Between polar regions: Hydrogen bonding (if applicable) or dipole - dipole interactions.
