Which of the following is a feature of an aromatic compound?
Which of the following is a feature of an aromatic compound?
It has a strong aroma.
Its formula contains only six carbon atoms.
It contains a benzene ring.
It contains only carbon-carbon double bonds.
I would choose c.
The feature of an aromatic compound among the given options is that it contains a benzene ring.
The feature of an aromatic compound among the given options is that it contains a benzene ring.
To determine this, you could start by understanding what an aromatic compound is. Aromatic compounds are a class of organic compounds with a specific structure known as a benzene ring. A benzene ring consists of a hexagon-shaped ring of carbon atoms, with three alternating double bonds and three single bonds.
Now, let's examine the given options:
1. "It has a strong aroma": While the name "aromatic" might suggest that these compounds have a strong aroma, this statement is not necessarily true. Aromatic compounds are named as such due to their historical relationship with strong aromas, but many aromatic compounds do not have a noticeable smell.
2. "Its formula contains only six carbon atoms": This statement refers to the size of the carbon skeleton, but it doesn't specifically relate to aromatic compounds. Aromatic compounds can have various numbers of carbon atoms in their formulas, so this statement is not accurate.
3. "It contains a benzene ring": This statement aligns with the feature of an aromatic compound. As mentioned earlier, a benzene ring is a key characteristic of aromatic compounds. Therefore, this option is correct.
4. "It contains only carbon-carbon double bonds": This option refers to a class of compounds known as alkenes, which are unsaturated hydrocarbons with one or more carbon-carbon double bonds. Although aromatic compounds can contain double bonds, they are not exclusively composed of double bonds; the alternating double bond pattern is specific to benzene rings. Therefore, this statement is not a feature specific to aromatic compounds.
In conclusion, the correct feature of an aromatic compound among the given options is that it contains a benzene ring.
