Answer 1

Answer:

Phenanthrene is a polycyclic aromatic hydrocarbon composed of three fused benzene rings. The name 'phenanthrene' is a composite of phenyl and anthracene. In its pure form, it is found in cigarette smoke and is a known irritant, photosensitizing skin to light.[citation needed] Phenanthrene appears as a white powder having blue fluorescence.

The compound with a phenanthrene skeleton and nitrogens at the 4 and 5 positions is known as phenanthroline.
