A clear liquid forms a layer when added to water. would you expect it to be organic or inorganic.

Answer 1

Water is a polar solvent because Oxygen (O) is more electronegative than Hydrogen (H), so the difference between electronegativities of H and O and its bent shape makes it a polar molecule. It has a high dielectric constant. So it dissolves a large number of substances. If a clear liquid forms a layer when added to water, it is expected to be organic, because organic compounds have a non-polar part (hydrocarbons) which is hydrophobic (water-repelling) and hence a lot of organic compounds are insoluble in water. A lot of inorganic substances like sodium (a metal), sodium chloride (an ionic compound) are soluble in water (except diamond which is an allotrope of carbon). So the layer of clear liquid formed over water is expected to be organic.
