Here in this example question it says name the following ether compound. In order to accomplish this we're going to utilize the following three steps.
Step one we have to identify the two alkyl groups connected to our oxygen atom. So here is our oxygen atom here and we have this alkyl group connected to it and this alkyl group connected to it here. This has 1, 2, 3, 4 carbons. So this would be a butyl group, and this is only a methyl group.
Step two name the two alkyl groups alphabetically as substituents. So here we're going to say we know we have a butyl and a methyl group connected to the oxygen. If there are identical alkyl groups, use the numerical prefix di. Here, they're not the same. So we don't have to say like dimethyl or dibutyl. So we're going to say here butyl methyl.
Step three end the name of the compound with ether and then write the name with spaces so there's a space between butyl and methyl and then the end of the name ether. So this would be butyl methyl ether.
