Multiple Choice

Which of the following can be classified as a haloarene?

The figure illustrates the structure of a molecule. A benzene ring is in a vertical orientation with C 1 occupying the topmost vertex. The ring contains alternating double bonds between C 1 and C 2, C 3 and C 4, and C 5 and C 6. C 2 is single bonded to B r.

The figure illustrates the structure of a molecule. A 5-carbon pentagonal ring is in a vertical orientation with C 1 occupying the topmost vertex. A double bond is present between C 2 and C 3 and C 4 and C 5. C 1 is single bonded to C l.

The figure illustrates the structure of a molecule. A 6-carbon hexagonal ring is in a vertical orientation with C 1 occupying the topmost vertex. A double bond is present between C 1 and C 2 and C 3 and C 4. C 2 is single bonded to I.

The figure illustrates the structure of a molecule. A 6-carbon alkene chain is depicted as a line structure using 5 lines bent in the form of an incomplete hexagon. A double bond is present between C 1 and C 2, C 3 and C 4, and C 5 and C 6. C 1 is single bonded to F on the upper right.

Verified step by step guidance

Understand the definition of a haloarene: A haloarene is an aromatic compound in which one or more hydrogen atoms in an aromatic ring are replaced by halogen atoms (such as F, Cl, Br, or I).

Identify the structure of each compound: Look at the images provided and identify the aromatic ring and the halogen attached to it.

Analyze the first image: The structure shows a benzene ring with a bromine atom attached, which is a typical haloarene structure.

Analyze the second image: The structure shows a cyclopentadiene ring with a chlorine atom attached. This is not a benzene ring, so it is not a haloarene.

Analyze the third and fourth images: Both structures show a benzene ring with iodine and fluorine atoms attached, respectively. These are also typical haloarene structures.
