Determine the systematic name of the molecule.

• A. ortho-fluoroisopropylbenzene
• B. para-fluoroisopropylbenzene
• C. meta-fluoroisopropylbenzene
• D. 1-fluoro-2-tert-butylbenzene

Answer: (A)

Verified step by step guidance

1. Identify the parent structure: The molecule is based on a benzene ring, which is a six-carbon aromatic ring.
2. Locate the substituents: There is a fluorine atom and an isopropyl group attached to the benzene ring.
3. Determine the positions of the substituents: The fluorine atom is attached to one carbon, and the isopropyl group is attached to the adjacent carbon on the benzene ring.
4. Assign the correct naming convention: The positions of the substituents are ortho to each other, meaning they are adjacent. In systematic naming, this is referred to as 1,2-disubstitution.
5. Combine the information: The systematic name should reflect the positions and types of substituents on the benzene ring, leading to the name 1-fluoro-2-isopropylbenzene.
