The addition in cycloalkanes is a type of chemical reaction that occurs between two organic compounds, through the opening of an aromatic cycle. This reaction is responsible for the formation of a new compound, with the presence of a different functional group. What is the chemical equation for the addition of bromine to cyclopropane?

Organic halides are compounds that have a halogen atom (F, Cl, Br, or I) bonded to a carbon atom belonging to a carbon chain. Their nomenclature depends on the rules established for organic compounds and is important for their identification and study. a) Given the compound 1-chloro-2-methylpropane, identify the functional groups present and write its structural formula. b) From the structural formula, simplify the representation (line formula) of the compound. c) Write the IUPAC nomenclature for the compound with the structural formula CH3CH2CH2Br.

One of the most fascinating aspects of Chemistry is the ability to transform and exist in different states of aggregation, depending on temperature and pressure conditions. The phase diagram is a powerful tool that helps us visualize and understand these transitions. Consider a system with a pure substance that can exist in the solid, liquid, and gaseous states. Based on the provided phase diagram, answer the following questions: 1) Identify the triple point and explain its importance in the study of phase equilibria. 2) Describe the anomalous behavior of water based on its phase diagram and discuss the biological and environmental implications of this phenomenon. 3) Select a point on the diagram and justify, based on the phase equilibrium lines, in which state the substance would be if subjected to those temperature and pressure conditions.
