Functional groups can be pretty much anything, TERM 2 Thiol DEFINITION 2 Thiols are the sulfur equivalent to alcohols. Rather than an - OH functional group, thiols just replace the oxygen with an S to give -SH (so alcohols are like "OH!" and thiols are like "- SH!+") TERM 3 Sulfides DEFINITION 3 Sulfides are the sulfur equivalent of ethers. They're just disubstituted sulfurs R-S-R'. Just remember "ROR, Rhinocerous!" or some other animal where R-S-R' can be an abbreviation for its name TERM 4 Naming Ethers DEFINITION 4 Hokay, ethers are easy to name. Just name the groups on either side of the ether and follow it with ether. So CH3-O- CH3 is just dimethly ether. If it's part of a functional group, then it's an oxy, so like O /\/ \ II I C(CH3)3 \/ Would be 4-tert- Butoxy-1-cyclohexene TERM 5 How to Make Ethers Williamson Reaction (SN2) DEFINITION 5 There are three ways (though I'm sure other methods exist) to make ethers. 1)Williamson synthesis- This dude's a freakin genius! Take an alcohol [Yeah, ethanol will work, but don't use PBr, that just confuses chemists :)] and hit it with a strong base, like NaH in THF. that makes it the oxygen all R-(-O). Then just hit it with an alkyl halide, like R-Br. DOn't use Cl, that's not as good a nucleophile. Br and I are a better choice.
