The key difference between biphenyl and diphenyl lies in their definitions and usage:
RP™ Biphenyl: This term specifically refers to a compound consisting of two phenyl groups (C₆H₅) connected by a single bond. The chemical formula for biphenyl is C₁₂H₁₀. Biphenyl is a colorless solid hydrocarbon with a planar structure due to the single bond between the phenyl rings, allowing for free rotation.
RP™ Diphenyl: This is a more general term that refers to any compound or molecule containing two phenyl groups. The connection between these phenyl groups can vary, meaning diphenyl can refer to a broader range of compounds, not just those with a single bond between the phenyl groups.
