Here are the essential concepts you must grasp in order to answer the question correctly.
Line-Angle Formula
The line-angle formula, also known as the skeletal formula, is a simplified way of representing organic molecules. In this representation, vertices and ends of lines represent carbon atoms, while hydrogen atoms are often omitted for clarity. This method allows chemists to visualize the structure of complex molecules quickly and efficiently, focusing on functional groups and connectivity.

Functional Groups
Functional groups are specific groups of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules. The nitro group (―NO₂) is a common functional group in organic chemistry, known for its role in explosives and pharmaceuticals. Understanding functional groups is essential for predicting the behavior and reactivity of organic compounds.

Isomers
Isomers are compounds that have the same molecular formula but differ in the arrangement of atoms, leading to different properties. In the case of TNT, 2,4,6-trinitrotoluene is one isomer, where the nitro groups are positioned at specific carbon atoms in the toluene ring. Recognizing isomers is crucial in chemistry as they can exhibit vastly different chemical behaviors despite having the same composition.
