Step 1: Locate the longest carbon chain containing the hydroxyl (-OH) functional group. This chain consists of five carbon atoms, establishing "pentane" as the base name for the parent chain.
Step 2: Assign numbers to the carbon chain, commencing from the extremity nearest to the -OH group. This numbering convention guarantees the -OH group receives the lowest possible locant. The hydroxyl group is situated on carbon 1, resulting in the designation "1-pentanol".
Step 3: Identify and enumerate any substituent groups attached to the main carbon chain. Two methyl groups are found on carbon atoms 3 and 4 of the principal chain.
Step 4: Assemble the nomenclature by integrating the names of the substituents, the parent chain, and the position of the -OH group. The resultant name is 3,4-dimethyl-1-pentanol.
Final Answer: 3,4-dimethyl-1-pentanol
