Phenanthrene is a polycyclic aromatic hydrocarbon (PAH) composed of three fused benzene rings, resulting in a bicyclic structure. It is a colorless crystalline solid at room temperature naturally found in coal tar, crude oil, and various fossil fuels. Phenanthrene is a prominent PAH family member and is a fundamental building block in organic chemistry and various industrial applications.
Chemical Structure:
Phenanthrene’s molecular formula is C14H10, and its structure consists of three benzene rings fused in a linear arrangement. The molecule is planar, with each carbon atom bonding aromatic and sigma. It exhibits aromaticity due to the delocalization of pi-electrons across the entire molecule.
Occurrence:
Phenanthrene occurs naturally in fossil fuels like coal, petroleum, and shale oil. It is formed during the incomplete combustion of organic matter, contributing to its presence in environmental matrices like soil, water, and air. Phenanthrene is also produced as a byproduct of various industrial processes, including coal gasification, oil refining, and combustion of organic materials.
