Anthracene is a solid polycyclic aromatic hydrocarbon (PAH) of formula C 14 H 10, consisting of three fused benzene rings. It is a component of coal tar . Anthracene is used in the production of the red dye alizarin and other dyes, as a Scintillator to detect high energy particles, as production of pharmaceutical drugs.
Structural formula of the benzocompound Benzocompound Anthracene: Benzo[a]anthracene: by adding four extra carbon atoms to the parent compound, the leftmost upper ring is formed. Phenanthrene: Benzo[b]fenanthrene: by adding four carbon atoms to the parent compound the right most ring is formed. Clearly this compound is identical to the compound ...
A Polycyclic aromatic hydrocarbon (PAH) is a class of organic compounds that is composed of multiple aromatic rings. Most are produced by the incomplete combustion of organic matter — by engine exhaust fumes, tobacco, incinerators, in roasted meats and cereals, [ 1 ] or when biomass burns at lower temperatures as in forest fires .
In the field of organic chemistry, a polycyclic compound is an organic compound featuring several closed rings of atoms, primarily carbon. [1] These ring substructures include cycloalkanes , aromatics , and other ring types.
Aromatic compounds, also known as arenes or aromatics, are chemical compounds that contain conjugated planar ring systems with delocalized pi electron clouds instead of discrete alternating single and double bonds. Typical aromatic compounds are benzene and toluene. They should satisfy Hückel's rule.
An aromatic π-sextet can be represented by a circle, as in the case of the anthracene molecule (below). Clar's rule states that for a benzenoid polycyclic aromatic hydrocarbon (i.e. one with only hexagonal rings), the resonance structure with the largest number of disjoint aromatic π-sextets is the most important to characterize its chemical ...
For loans, simple interest is based on only the principal amount, whereas compound interest is based on the principal and interest combined. A savings account grows more quickly by earning ...
Benz[a]anthracene or benzo[a]anthracene is a polycyclic aromatic hydrocarbon with the chemical formula C 18 H 12. [2] It is produced during incomplete combustion of organic matter. Benz[ a ]anthracene is one of carcinogenic constituents of tobacco smoke .
