Why is acenaphthylene aromatic?
Acenaphthylene is a polycyclic aromatic hydrocarbon (PAH). Like many PAHs, it is used in dyes, pesticides, soaps, and plastics. It could be confusing that acenaphthylene is an aromatic compound, because at first glance it appears to break Huckel’s rule of aromaticity because it has 12 pi electrons.
Chemical Properties ANTHRACENE is a colorless solid; melting point 218 °C, blue fluorescence when pure; insoluble in water, slightly soluble in alcohol or ether, soluble in hot benzene, slightly soluble in cold benzene; transformed by sunlight into para -anthracene (C14H10)2.
What is the formula of phenanthrene?
C14H10
Phenanthrene/Formula
Phenanthrene a polycyclic aromatic hydrocarbon (PAH) with formula C14H10, consisting of three fused benzene rings. It is a colorless, crystal-like solid, but can also appear yellow.
Is acenaphthene soluble in water?
Acenaphthene appears as white needles. Melting point 93.6°C. Soluble in hot alcohol. Denser than water and insoluble in water.
Why is anthracene not soluble in water?
Many drugs are hydrophobic, which makes them poorly soluble in water. Anthracene will be 25 times less soluble than phenanthrene in every solvent we care to try. The black portions of the bars are a property of the solid and are completely unaffected by the choice of solvent.
What’s the melting point of acenaphthene in water?
Melting point 93.6°C. Soluble in hot alcohol. Denser than water and insoluble in water. Hence sinks in water. May irritate skin and mucous membranes. Emits acrid smoke and irritating fumes when heated to decomposition. Derived from coal tar and used to make dyes, pharmaceuticals, insecticides, fungicides, and plastics.

Which is not to be confused with acenaphthene?
Not to be confused with Acenaphthylene. Acenaphthene is a polycyclic aromatic hydrocarbon (PAH) consisting of naphthalene with an ethylene bridge connecting positions 1 and 8. It is a colourless solid. Coal tar consists of about 0.3% of this compound.
How is acenaphthene derived from naphthalene and ethylene?
Acenaphthene is a polycyclic aromatic hydrocarbon derived from naphthalene by the addition of an ethylene bridge connecting C-1 and C-8.
