You're going to say that THS also called mercaptan possess a mercapto group or capital just means sh group connected to a carbon atom. Now, the set of rules for naming THS are very similar to the ones used to name alcohols. Now, here, all we do is we add th to the parent chain name. So our naming convention will be the location of our different substituents. Then we have the location and then parent and then our file name, right? So this is the way we would approach when it comes to naming different types of files.

Name the following file compound, right? So step one says to find the longest carbon chain because it'll represent the parrot chain and assign name according to the prefixes. Now, the parrot chain should include the SH group, the Mecca Mercapto group and have the largest number of carbons. If a tie between longest chain, choose chain with more substituents. If we take a look here, our longest chain would have to be this chain. Now, we have our longest chain. So we have to, let's see, assign name according to the prefix. We're going to assign name to all the substituents here. So we know that this SH group is gonna become a file. Um It's gonna form um near the end of the name. So we won't worry about it. We have BR here, which is BROMO and one carbon here is methyl step three as we start numbering the chain from the end closest to the SH group. So the end close to the SH group is here 123456. If I tie the number from N, close to the next substituent, if it's still a tie number in alphabetical order, assign numerical location to the carbon with the SH group, which we did then 4 to 6 were repeat steps from previous naming topics. So here this is what it would look like. All right. So we say we have BROMO and methyl, we named those alphabetically. So, bromo is on three, so three bromo, five methyl. Then we're going to say that the thiol group, the mercapto group is on carbon T. So two, it's a six carbon chains. So Hexane file, OK. So this would be the name of this particular file compound.
