The general format for this kind of naming is: (positions of substituents (if >1)- + # (di, tri.) + substituent)n + benzene. For example, chlorine (Cl) attached to a phenyl group would be named chlorobenzene (chloro + benzene).
How do you name polycyclic compounds?
Naming Fused and Bridged Compounds
- Count the total number of carbons in both rings. This is the parent name.
- Count the number of carbons between the bridgeheads, then place the numbers in square brackets in descending order separated by periods.
- Place the word bicyclo at the beginning of the name.

Is anthracene an aromatic compound?
Abstract. Anthracene is a solid polycyclic aromatic hydrocarbon (PAH) consisting of three fused benzene rings. It is a component of coal-tar and the US Occupational Health and Safety Administration classifies it as noncarcinogenic. Anthracene is used in the production of the red dye alizarin and other dyes.
How do you name spiro compounds?
IUPAC names for spiro alkanes have the format spiro[a.b]parent name.
- Count the total number of carbons across the entire molecule.
- Count the number of carbons to the left, and to the right of your spiro-carbon center.
- Write your final IUPAC name as spiro[a.b]parent name.
Which position of anthracene gives?
Electrophilic substitution occurs at the “9” and “10” positions of the center ring, and oxidation of anthracene occurs readily, giving anthraquinone, C14H8O2 (below).
What is the nature of anthracene?
neutral in nature
Anthracene present in coal tar is neutral in nature. Other neutral hydrocarbons include benzene, toluene, and naphthalene.
