The IUPAC name for the compound with benzene and a hydroxyl group in the ortho position is orthophenol. This systematic nomenclature reflects the specific arrangement of the substituent relative to the benzene ring, ensuring clear and standardized chemical communication.
The compound with benzene and a hydroxyl (OH) group in the ortho position is named orthophenol, according to IUPAC nomenclature. The IUPAC name follows systematic rules for naming organic compounds. In this case:
1. **Parent Hydrocarbon:** Benzene
2. **Substituent:** Hydroxyl group (OH)
3. **Position of Substituent:** Ortho position (next to the reference carbon)
Putting it together, the IUPAC name is orthophenol. The term "ortho" denotes the specific position of the substituent relative to the benzene ring. Phenol refers to a benzene ring with a hydroxyl group attached. This naming convention provides a clear and standardized way to describe the structure of organic compounds, ensuring consistency in chemical communication and understanding.
