The position of functional groups like -OH in alcohols or -COOH in carboxylic acids determines the IUPAC name. Count the carbon atoms in the longest chain, and use the appropriate suffix based on the functional group.
(i) IUPAC Name of the First Compound:
The given compound is an alcohol with 3 carbon atoms and a hydroxyl group (-OH) attached to the terminal carbon atom. The IUPAC name is Propan-2-ol, as the alcohol group is on the second carbon of the chain.
(ii) IUPAC Name of the Second Compound:
The second compound is a carboxylic acid with a 6-carbon chain. The functional group is a hydroxyl group (-OH) at the end of the chain, and it is a hexanoic acid. The IUPAC name is Hexanoic acid.
Conclusion:
1. The IUPAC name for the first compound is Propan-2-ol.
2. The IUPAC name for the second compound is Hexanoic acid.
