Here are the essential concepts you must grasp in order to answer the question correctly.
Electrophilic Addition Reactions
Electrophilic addition reactions are a fundamental type of reaction in organic chemistry where an electrophile reacts with a nucleophile, typically involving alkenes or alkynes. In the presence of bromine (Br2), these unsaturated compounds can undergo addition, resulting in the formation of vicinal dibromides. Understanding this mechanism is crucial for predicting the products when compounds are treated with Br2.

Reaction Conditions and Temperature Effects
The temperature at which a reaction occurs can significantly influence the reaction pathway and the products formed. At elevated temperatures, such as 125 °C, reactions may favor different mechanisms or lead to the formation of more stable products. Recognizing how temperature affects reaction kinetics and thermodynamics is essential for interpreting the outcomes of organic reactions.

Stereochemistry of Addition Reactions
Stereochemistry refers to the spatial arrangement of atoms in molecules and how this affects their chemical behavior. In electrophilic addition reactions, the stereochemical outcome can lead to different isomers, such as cis and trans forms. Understanding stereochemistry is vital for predicting the specific products formed when compounds react with bromine, especially in terms of their spatial configuration.
