It is known that acetone is a type of ketone widely used as a solvent in the industry, mainly for the production of plastics, paints, and varnishes. Furthermore, studies show that its use can pose risks to human health and the environment. Considering the context, answer: a) Describe the general structure of a ketone and what sets it apart from other functional groups. b) Identify and explain some of the risks associated with exposure to acetone for health and the environment. c) Propose individual and collective measures that can be adopted to reduce the negative impacts caused by the responsible use and disposal of acetone.

Nitro compounds are organic compounds that have one or more nitro groups (NO2) directly attached to a carbon atom of an alkyl or aryl group. They are commonly used as explosives due to their ability to rapidly decompose and release gases. Considering the IUPAC nomenclature rules for nitro compounds, answer: a) What is the correct nomenclature for the compound CH3CH2NO2? b) Write the molecular structure of 2,4-dinitrotoluene and identify the functional groups present in the molecule. c) According to the IUPAC rules, what is the name of the organic compound formed by substituting the three hydrogens of methane with three nitro groups?
