Question 1

What is the definition of an aromatic compound?

Answer 1

Aromatic compounds are cyclic, planar, conjugated compounds with a delocalized pi electron system.

Question 2

True or False: All aromatic compounds contain a benzene ring.

Answer 2

False. While benzene is a common example of an aromatic compound, not all aromatic compounds contain a benzene ring.

Question 3

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?

Answer 3

Huckel’s rule

Question 4

Fill in the blank: Aromatic compounds are more __________ than non-aromatic compounds.

Answer 4

stable

Question 5

Which type of aromatic compound has alternating single and double bonds and obeys Huckel’s rule?

Answer 5

benzene

Question 6

What is the name of the process where an aromatic ring is substituted with a functional group?

Answer 6

Aromatic substitution

Question 7

True or False: Aromatic compounds are highly reactive due to their stability.

Answer 7

False. Aromatic compounds are relatively stable and less reactive compared to non-aromatic compounds.

Question 8

What is the term for a compound that contains both aromatic and non-aromatic rings?

Answer 8

Polycyclic aromatic hydrocarbon (PAH)

Question 9

What is the name of the rule that determines if a compound obeys aromaticity based on the number of pi electrons?

Answer 9

Huckel’s rule

Question 10

Which aromatic compound is commonly found in essential oils and has a characteristic smell?

Answer 10

Benzaldehyde

Question 11

Fill in the blank: Aromatic compounds often undergo __________ reactions due to their stability.

Answer 11

substitution

Question 12

True or False: Aromatic compounds have a higher degree of unsaturation compared to non-aromatic compounds.

Answer 12

False. Aromatic compounds have a lower degree of unsaturation due to their stability.

Question 13

What is the name of the compound that consists of a benzene ring with a hydroxyl group attached?

Answer 13

Phenol

Question 14

Which rule states that for a molecule to be aromatic, it must have 4n+2 pi electrons?

Answer 14

Huckel’s rule

Question 15

True or False: Aromatic compounds are always planar in structure.

Answer 15

True

Question 16

What is the term for the process where an aromatic compound loses its aromaticity?

Fill in the blank: Aromatic compounds exhibit a ________ system of electrons delocalized over the ring.

Answer 18

pi

Question 19

Which type of aromatic compound is highly reactive and undergoes electrophilic aromatic substitution?

Answer 19

Phenol

Question 20

What is the name of the process where an aromatic compound gains an electron to become an anion?

Answer 20

Aromatic nucleophilic substitution

Question 21

True or False: Aromatic compounds are more likely to undergo addition reactions than substitution reactions.

Answer 21

False. Aromatic compounds are more likely to undergo substitution reactions due to their stability.
