Give the systematic name for the following ether. Now, here, step 1 is we have to identify the two alkyl groups connected to the oxygen atom. And we're going to say that the larger alkyl group is assigned the parent name according to the prefixes. So if we take a look at this ether, this side here has a total of four carbons involved. So if we look, we have four carbons involved here, and this side only has two. So, it's going to be the one on the left side that's going to form the parent name. Step 2 is we have to assign names to all substituents.
Alright. So, the way we're going to look at this is this side has the most carbons involved, but we still have to operate along the whole idea of substituents and the longest chain. We're going to say that the smaller alkyl by default will become the alkoxy substituent, and it'll be connected to the oxygen. So here, this is a substituent for us. So this is a substituent. And we have to look and see what the longest carbon chain is. The longest carbon chain is 123, which would mean that this up here is also a substituent.
Right, so we have two substituents on a three-carbon chain. Alright, so start numbering the chain from the, we're going to say the closest substituent. If a tie between substituents compare the next closest substituent, there was no tie because if we made this carbon 1, that's because the substituent's already here. If we made this 1, we'd have to go 12 before we get to a substituent. Right now, if still a tie, then number in alphabetical order, which we didn't need to do.
Alright. So we have our structure here. Again, this is a substituent, and this becomes a substituent. And then we repeat steps from naming alkanes with substituents. So coming back up here, We're going to say that this is a one-carbon substituent, so this is a methyl. This here is an alkoxy substituent since it's combined with the oxygen. A 2-carbon substituent is ethyl, but it's no longer an ethyl because it's combined with the oxygen, so it becomes an ethoxy.
Alright. So now we're going to say that the longest carbon chain is three carbons long, three carbons long is propane. And then the two substituents e come before m. So on carbon 1, we have an ethoxy. On carbon 2, we have a methyl. So this would be 1-ethoxy-2-methylpropane. This will be the name of this following ether.
