Propanone is widely used in industry and in the laboratory as
Correct answer: A. a solvent, because it dissolves both polar and non polar substances and evaporates quickly
- A. a solvent, because it dissolves both polar and non polar substances and evaporates quickly
- B. an oxidising agent
- C. a fuel for vehicles
- D. a food preservative
Explanation
Its polar carbonyl group and small hydrocarbon portion let propanone dissolve a wide range of materials, and its low boiling point of 56 degrees Celsius means it dries rapidly, which is why it is used as nail polish remover and for cleaning glassware. It is also miscible with water in all proportions. Being highly flammable, it must be kept away from flames.

About Preparation of Aldehydes and Ketones
Aldehydes and ketones are prepared mainly by controlled oxidation or dehydrogenation of primary and secondary alcohols, respectively. The topic also includes ozonolysis of alkenes, hydration of alkynes and preparation through acyl derivatives, with attention to why primary alcohols can give aldehydes whereas secondary alcohols give ketones.
