👉 Biphenyls are a group of aromatic compounds that contain three fused carbon atoms. They have been used in various industrial processes for their unique properties, such as resistance to corrosion and low cost. These compounds can be classified into two main groups based on their molecular structure:
1.
Phenyl Group
: This group contains only one fused carbon atom and is known for its strong aromaticity and high boiling point. Examples include benzene (C6H6), toluene (C
