Verified step by step guidance1
Identify the longest carbon chain that contains the highest priority functional group. In this case, the longest chain is a heptene (7 carbon atoms) with a double bond.
Number the carbon chain starting from the end nearest to the double bond to give the lowest possible numbers to the double bond and substituents. The double bond starts at carbon 3.
Identify and name the substituents attached to the main chain. Here, there is an isopropyl group attached to carbon 3 and a thiol group (SH) attached to carbon 2.
Combine the names of the substituents with the main chain name, placing the substituents in alphabetical order and using the appropriate locants. The isopropyl group is named before the thiol group.
The IUPAC name is constructed as: 3-isopropyl-3-heptene-2-thiol, ensuring that the substituents and functional groups are correctly positioned and named according to IUPAC rules.
