Is biphenyl aromatic or non aromatic?
Biphenyl is an aromatic hydrocarbon with a molecular formula (C6H5)2. The biphenyl molecule consists of two connected phenyl rings.
Why biphenyl is non aromatic?
Biphenyl has 12 π-electrons and according to Hückel’s rule, it should not be aromatic because 12≠4n+2, but it nevertheless is aromatic.
What is the melting point of biphenyl?
156.6°F (69.2°C)

Why biphenyl is an aromatic compound?
Biphenyl is a benzenoid aromatic compound that consists of two benzene rings connected by a single covalent bond. Biphenyl occurs naturally in coal tar, crude oil, and natural gas. Formerly used as a fungicide for citrus crops.
Is biphenyl A PAH?
Another type of polycyclic aromatic hydrocarbon contains two or more benzenoid rings joined by a carbon-carbon single bond. The simplest compound of this type is biphenyl, the compound from which PCBs (polychlorinated biphenyls) are derived.
