Answer
option (d) is correct.
Work Step by Step
The word hydrophilic means attraction to water. Molecules tend to be hydrophilic when they have functional groups that can form hydrogen bonds with molecules of water. Hence, option (a) is correct. The term polar refers to molecules that have chemical groups with an electric dipole or multiple moment. Polar molecules make interactions through dipole-dipole interactions. The existence of a dipole enables the molecules to do form hydrogen bonds with water molecules. Hence, option (b) is correct. Fatty acids are composed of a hydrophilic carboxyl head and a long hydrocarbon chain that is hydrophobic in nature. Hence, option (c) is correct. Hydrophilic means propensity towards the water. The term opposite in meaning to hydrophilic is hydrophobic, which means away from water. Hence, option (d) is correct.
Since all the given options are correct, the correct answer is an option (e) all of the above.
