### Related Formula Principal functional group priority rules: -textOH > textAlkene$-\text{OH} > \text{Alkene}$. ### Core Logic According to IUPAC nomenclature priority rules, the principal functional group is the alcohol group (-textOH$-\text{OH}$). The ring numbering starts at the carbon containing the -textOH$-\text{OH}$ group as C1. Numbering then proceeds towards the double bond to give it the lowest possible position numbers. This designates C2 and C3 for the double bond carbons, making it a 'cyclohex-2-en-1-ol'. ### Step 1: Final Assignment Hence, combining the root and suffix gives the correct systematic designation: Cyclohex-2-en-1-ol. ### Pattern Recognition Always number functional cyclic systems to prioritize principal suffixes (-textOH$-\text{OH}$) first, then provide minimal numbers to unsaturation points. ### Evaluation Rubric / Model Answer null ### Chapter Mix Class 11 Chemistry: Nomenclature of Organic Compounds
