Final answer:
The types of intermolecular interactions that would occur between the dyes in known sample 1 (fd) are dipole-dipole interactions and dispersion forces.
Step-by-step explanation:
The types of intermolecular interactions that would occur between the dyes in known sample 1 (fd) are dipole-dipole interactions and dispersion forces.
Dipole-dipole interactions occur between polar molecules and are caused by the attraction between the positive end of one molecule and the negative end of another molecule.
Dispersion forces, also known as London dispersion forces, occur between all molecules and are caused by temporary shifts in electron density that create temporary dipoles.
