how do molecules attract each other when they are dying predict how ethanol would interact with the food dye molecues

Kindly check the explanation section.

Explanation:

Chemical bonding is a very important concept in chemistry. It involves the bonding of atoms, molecules and/or compounds.

There are different ways in which molecules get attracted to each other. The bonding may be through induced dipole interaction, ionic bonding, hydrogen bonding,  Van-der wal interaction, or through covalent bonding.

For the second part of the question. The question asked to predict how ethanol would interact with the food dye molecules.

Ethanol bonds with food dye molecules through one of the chemical bonding known as the Hydrogen bond. Which is as a result of the bonding between hydrogen atoms and another atom which is much more electronegative than Hydrogen atoms.
