Here are the essential concepts you must grasp in order to answer the question correctly.
Condensed Structures
Condensed structures are a simplified way of representing molecular structures where atoms are grouped together to show connectivity without depicting all bonds explicitly. In these structures, carbon atoms are often listed in a linear format, and hydrogen atoms attached to them are implied rather than shown. This notation helps in quickly visualizing the molecular framework while maintaining clarity about the arrangement of atoms.

Skeletal Structures
Skeletal structures, also known as line-angle structures, are a shorthand representation of organic molecules where carbon atoms are represented by vertices and hydrogen atoms are omitted for clarity. Each vertex represents a carbon atom, and the lines between them represent bonds. This method is particularly useful for complex molecules, as it allows chemists to easily visualize the overall shape and connectivity of the molecule without cluttering the diagram with hydrogen atoms.

Isopropylacetylene
Isopropylacetylene is an alkyne compound characterized by a triple bond between two carbon atoms, with an isopropyl group (a branched alkyl group) attached to one end. Its structure can be derived from acetylene by substituting one hydrogen atom with an isopropyl group. Understanding the structure of isopropylacetylene is essential for accurately drawing its condensed and skeletal forms, as it influences the overall geometry and reactivity of the molecule.
