Solution
Solution Steps
Step 1: Identify the parent chain
The longest carbon chain containing the highest-priority functional group (thiol) has four carbons, making the parent chain butane. The thiol group takes priority over the hydroxy group, so we number the chain starting from the sulfur. The suffix will be -thiol since thiol is the highest priority group.
Step 2: Identify and number the substituents
There is a hydroxy group on carbon 3 and a substituted phenyl ring at carbon 2. The substituents on the phenyl ring are an ethoxy group at carbon 3 and a methylthiomethyl group at carbon 5. Numbering of the phenyl ring starts at the point of attachment to the butane chain.
Step 3: Assemble the name
Combining all the substituents and the parent chain, and ordering them alphabetically, we obtain the IUPAC name.
