Step 1: Analyze the structure of compound (i). Identify the longest continuous carbon chain that includes the triple bond and double bond. This will serve as the parent chain.
Step 2: Number the parent chain in compound (i) starting from the end closest to the triple bond, as it has higher priority over the double bond. Assign locants to the triple bond, double bond, and substituents.
Step 3: Name the substituents in compound (i) (e.g., methyl groups) and include their positions in the name. Combine the substituents, parent chain, and locants into the systematic name, ensuring proper use of IUPAC nomenclature rules.
Step 4: For compound (ii), identify the longest continuous carbon chain that includes the triple bond and the hydroxyl group (-OH). The parent chain should prioritize the functional group (-OH) over the triple bond.
Step 5: Number the parent chain in compound (ii) starting from the end closest to the hydroxyl group (-OH). Assign locants to the hydroxyl group, triple bond, and substituents. Name the substituents and combine them with the parent chain and locants to form the systematic name, ensuring correct IUPAC nomenclature.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
IUPAC Nomenclature
IUPAC nomenclature is a systematic method for naming organic chemical compounds. It provides rules for identifying the structure of a compound based on its molecular formula and functional groups. Understanding the hierarchy of functional groups, the longest carbon chain, and the correct use of prefixes and suffixes is essential for accurately naming compounds.
Functional groups are specific groups of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules. Common functional groups include alcohols, alkenes, and alkynes, each influencing the compound's reactivity and properties. Recognizing these groups is crucial for determining the systematic name of a compound.
Structural isomerism occurs when compounds have the same molecular formula but different structural arrangements of atoms. This can lead to variations in physical and chemical properties. Understanding structural isomerism is important for naming compounds, as different structures can result in different IUPAC names despite having the same molecular formula.
