Answer: Chloroethane and chlorobenzene are two different chemical compounds with distinct physical and chemical properties.
Step-by-step explanation: Here are some tests that can be used to distinguish between the two:
Solubility: Chloroethane is soluble in water, while chlorobenzene is insoluble in water. This can be used to distinguish between the two by adding a small amount of each compound to water and observing whether or not it dissolves.
Density: Chloroethane has a higher density than chlorobenzene, so the two can be distinguished by measuring their densities.
Boiling point: Chloroethane has a lower boiling point than chlorobenzene, so the two can be distinguished by measuring their boiling points.
Infrared spectroscopy: Both chloroethane and chlorobenzene have distinctive infrared spectra, which can be used to identify them.
NMR spectroscopy: Nuclear magnetic resonance (NMR) spectroscopy can also be used to distinguish between chloroethane and chlorobenzene, as each compound has a unique NMR spectrum.
Chromatography: Chromatography techniques such as gas chromatography (GC) or liquid chromatography (LC) can be used to separate and identify the two compounds.
