Which of the following compounds is an example of a para-substituted aromatic compound?

Which of the following compounds is an example of a para-substituted aromatic compound?

Step 1: Understand what an aromatic compound is. Aromatic compounds contain a benzene ring, which is a six-carbon ring with alternating double bonds.
Step 2: Learn about substituents. A substituent is an atom or group of atoms that replaces a hydrogen atom on the benzene ring.
Step 3: Identify the positions on the benzene ring. The positions are labeled as ortho (adjacent), meta (one carbon apart), and para (opposite sides of the ring).
Step 4: Look for examples of para-substituted compounds. A para-substituted compound has two substituents located at the 1 and 4 positions on the benzene ring.
Step 5: Check the example given: p-Dichlorobenzene has two chlorine atoms at the 1 and 4 positions, making it para-substituted.
