What is the definition of an aromatic compound?
Aromatic compounds are cyclic, planar, conjugated compounds with a delocalized pi electron system.
True or False: All aromatic compounds contain a benzene ring.
False. While benzene is a common example of an aromatic compound, not all aromatic compounds contain a benzene ring.
What is the name of the rule that states for a molecule to be aromatic, it must be cyclic, planar, and obey Huckel’s rule?
Huckel’s rule
Fill in the blank: Aromatic compounds are more __________ than non-aromatic compounds.
stable
Which type of aromatic compound has alternating single and double bonds and obeys Huckel’s rule?
benzene
What is the name of the process where an aromatic ring is substituted with a functional group?
Aromatic substitution
True or False: Aromatic compounds are highly reactive due to their stability.
False. Aromatic compounds are relatively stable and less reactive compared to non-aromatic compounds.
What is the term for a compound that contains both aromatic and non-aromatic rings?
Polycyclic aromatic hydrocarbon (PAH)
What is the name of the rule that determines if a compound obeys aromaticity based on the number of pi electrons?
Huckel’s rule
Which aromatic compound is commonly found in essential oils and has a characteristic smell?
Benzaldehyde
Fill in the blank: Aromatic compounds often undergo __________ reactions due to their stability.
substitution
True or False: Aromatic compounds have a higher degree of unsaturation compared to non-aromatic compounds.
False. Aromatic compounds have a lower degree of unsaturation due to their stability.
What is the name of the compound that consists of a benzene ring with a hydroxyl group attached?
Phenol
Which rule states that for a molecule to be aromatic, it must have 4n+2 pi electrons?
Huckel’s rule
True or False: Aromatic compounds are always planar in structure.
True
What is the term for the process where an aromatic compound loses its aromaticity?
Aromaticity loss
What is the name of the compound with a six-membered aromatic ring containing a nitrogen atom?
Pyridine
Fill in the blank: Aromatic compounds exhibit a ________ system of electrons delocalized over the ring.
pi
Which type of aromatic compound is highly reactive and undergoes electrophilic aromatic substitution?
Phenol
What is the name of the process where an aromatic compound gains an electron to become an anion?
Aromatic nucleophilic substitution
True or False: Aromatic compounds are more likely to undergo addition reactions than substitution reactions.
False. Aromatic compounds are more likely to undergo substitution reactions due to their stability.
What is the name of the compound that contains a benzene ring with a methyl group attached?
Toluene
Which type of aromatic compound has a nitrogen atom in the ring and is a common building block in organic synthesis?
Pyridine
