Step 1: Understand what an aromatic compound is. Aromatic compounds are usually cyclic (ring-shaped) and have a specific type of stability due to their electron structure.
Step 2: Identify the structure of the compounds given in the question. Look for a ring structure in the compounds.
Step 3: Check if the compound has delocalized pi electrons. This means that the electrons are shared across the entire ring rather than being localized between two atoms.
Step 4: Determine if the compound follows Huckel's rule, which states that for a compound to be aromatic, it must have (4n + 2) pi electrons, where n is a non-negative integer.
Step 5: Conclude that benzene is aromatic because it is cyclic, has delocalized pi electrons, and follows Huckel's rule with 6 pi electrons (n=1).
