Here are the essential concepts you must grasp in order to answer the question correctly.
Condensed Structural Formula
A condensed structural formula is a way of representing a chemical compound that shows the arrangement of atoms and the connectivity between them without depicting all the bonds explicitly. It typically uses symbols for atoms and groups, allowing for a more compact representation. For example, in a condensed formula, multiple carbon atoms can be grouped together, simplifying the visual complexity of larger molecules.

Geometric Isomerism
Geometric isomerism occurs in compounds with restricted rotation around a double bond, leading to different spatial arrangements of atoms. In the case of trans-1-bromo-2-chloroethene, the 'trans' designation indicates that the bromine and chlorine substituents are on opposite sides of the double bond. Understanding this concept is crucial for accurately drawing the structure and recognizing the compound's properties.

Substituents in Organic Chemistry
Substituents are atoms or groups of atoms that replace hydrogen atoms in a hydrocarbon chain, influencing the chemical properties and reactivity of the compound. In trans-1-bromo-2-chloroethene, the bromine and chlorine are the substituents on the ethene backbone. Identifying and correctly placing these substituents is essential for constructing the accurate condensed structural formula.
