Here are the essential concepts you must grasp in order to answer the question correctly.
Hydrogen Bonding
Hydrogen bonding is a type of intermolecular force that occurs when a hydrogen atom covalently bonded to a highly electronegative atom, such as oxygen or nitrogen, interacts with another electronegative atom. This interaction is crucial for the solubility of compounds in polar solvents like ethanol, as it enhances the attraction between the solute and solvent molecules.

Polarity of Molecules
Polarity refers to the distribution of electrical charge over the atoms in a molecule. Polar molecules, which have a significant difference in electronegativity between their atoms, can interact favorably with polar solvents like ethanol. Understanding the polarity of the given compounds helps predict their ability to form hydrogen bonds with ethanol.

Functional Groups
Functional groups are specific groups of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules. In the context of the question, identifying functional groups such as hydroxyl (-OH) in CH3CH2OCH2CH2OH or amine (-NH) in CH3CH2N(CH3)2 is essential, as these groups can participate in hydrogen bonding with ethanol.
