- 1what is a derivative of benzene called?aromatic
- 2how do you name a monosubstituted benzene?benzene is the parent name, such as "chlorobenzene"
- 3name the mono substituted aromatic compoundssee
- 4how is a benzene compound named if the parent chain is larger than the benzene? (it must have more than 6 carbon atoms)the benzene ring is treated as a substituent and is called a phenyl group
- 5what are dimethyl derivatives of benzene called?xylene
- 6what are the three constitutionally isomeric xylene?ortho, meta, and para
- 7how is a benzene compound named if it has 3 or more substituents?ortho, para, and meta cannot be used, so they must be named regularly with locants and common names
- 8what does resonance describe?resonance is the way that chemists deals with the inadequacy of bond line drawings
- 9why do benzene rings not undergo addition reactions?they would lose their stability, so it is unfavorable
- 10what is the source of benzene stability?the closed shell electron configuration
- 11what is huckels rule?a compound can only be aromatic if it has an odd number of electron pairs, which can be expressed as 4n + 2pi
- 12what is the criteria for non aromatic?to be aromatic, the compound must obtain a ring compromised of continuously overlapping p orbitals. if it does not have this, it is non aromatic
- 13what is the criteria for anti aromatic?if it has a continuous pi system but does have 4n electrons rather than 4n+2
- 14what are cyclic compounds called when they contain hetero atoms?heterocycles
- 15how do you compare stability of polycyclic aromatic hydrocarbons (PAHs)?comparing heat of hydrogenation
