What is the type of particles present in naphthalene?
Naphthalene is an aromatic hydrocarbon comprising two fused benzene rings.

How will you show that naphthalene has two benzene rings fused in o position?
It is the simplest polycyclic aromatic compound which contain two benzene rings fused together at the ortho bond. Naphthalene contains 5 C=C bonds in the closed loop. Naphthalene contain 10 π electrons. So, according to Hückel’s Rule (n=2) naphthalene obeys (4n+2)π electron rule.
What is the property of naphthalene?
Properties of Naphthalene: Naphthalene is generally white in colour. It is also found in transparent to brownish colour. The molecular weight of naphthalene is 128.18 g/mol. Naphthalene is insoluble in water at a normal room temperature.
Are all CC bond lengths equal in naphthalene?
The carbon-carbon bond lengths in naphthalene are not equal because as an aromatic hydrocarbon, naphthalene’sstructure consists of a fused pair of benzene rings. Hence , it consists of alternating single and double bonds with different bond lengths.
What is the 2D chemical structure image of naphthalene?
The 2D chemical structure image of naphthalene is also called skeletal formula, which is the standard notation for organic molecules.
Where are the carbon atoms located in naphthalene?
The carbon atoms in the chemical structure of naphthalene are implied to be located at the corner (s) and hydrogen atoms attached to carbon atoms are not indicated – each carbon atom is considered to be associated with enough hydrogen atoms to provide the carbon atom with four bonds.
Is naphthalene a polycyclic aromatic hydrocarbon (PAH)?
(In organic chemistry, rings are fused if they share two or more atoms.) As such, naphthalene is classified as a benzenoid polycyclic aromatic hydrocarbon (PAH). The eight carbons that are not shared by the two rings carry one hydrogen atom each.
What is the CID number for naphthalene?
