Is phenanthrene a hydrocarbon?
A polycyclic aromatic hydrocarbon composed of three fused benzene rings which takes its name from the two terms ‘phenyl’ and ‘anthracene.
What is the density of phenanthrene?
What are the properties of phenanthrene?
The phenanthrene is a colorless crystal with luster, and the phenanthrene precipitated from ethanol is a colorless monoclinic crystal. The phenanthrene is a leaf-like crystal with a relative density of 1.179 (25/4 ℃) and a refractive index of 1.6450, melting point of 101 °C and boiling point of 340 °C.
What is the molecular weight of phenanthrene?
Why is the phenanthrene 9 10 more reactive?
The 1,2 bonds in both naphthalene and antracene are in fact shorter than the other ring bonds, whereas the 9,10 bond in phenanthrene closely resembles an alkene double bond in both its length and chemical reactivity.
Is phenanthrene soluble in methanol?
Phenanthrene is a polycyclic aromatic hydrocarbon (PAH) which is a byproduct in gas plants and can be used in dye, explosive, and pharmaceutical industries….Introduction.
|water to solvent||methanol|
Is phenanthrene an acid?
It has also been used to make bile acids, cholesterol and steroids. Phenanthrene occurs naturally and also is a man-made chemical….Phenanthrene.
How many resonating structures are there for phenanthrene?
five resonating structures
– The resonating structures of Phenanthrene are as follows. – Therefore Phenanthrene shows five resonating structures.
Why 9/10 position of anthracene are very reactive?
The reaction is sensitive to oxygen. In most other reactions of anthracene, the central ring is also targeted, as it is the most highly reactive. Electrophilic substitution occurs at the “9” and “10” positions of the center ring, and oxidation of anthracene occurs readily, giving anthraquinone, C14H8O2 (below).
Which position is more reactive in phenanthrene?
Orientation in the substitution of naphthalene can be complex, although the 1 position is the most reactive.
What is the solubility of naphthalene in methanol?
Treatment with methanol alone gives low extraction efficiency although its recovery by crystallization and precipitation of naphthalene is very easy. This is due to a solubility of 5.3% methanol in the fuel and a rapid saturation of 6% of naphthalene in methanol .
Does phenanthrene dissolve in water?
Phenanthrene is nearly insoluble in water but is soluble in most low polarity organic solvents such as toluene, carbon tetrachloride, ether, chloroform, acetic acid and benzene.
