Indeed, as Trevor H says, the IUPAC way of naming is to treat the shorter chain with the oxygen as a substituent on the larger alkyl residue. So this needs a bit more detail than he's put. The other answerer made allowance for this by naming it as ethyl n-butyl ether the 'n-butyl' showing the CH2-CH2-O- was joined to the end of the butyl group. Ethers R-O-R consist of an oxygen atom between the two attached carbon chains.
The shorter of the two chains becomes the first part of the name with the -ane suffix changed to -oxy, and the longer alkane chain becomes the suffix of the name of the ether.
I don't know why everyone is saying it's an ether That's the formula for methadone, which is an opioid, NOT an ether. Trending News. Sheen was 'winning' 10 years ago. Now he has regrets. Through the use of chiral methyl groups, the stereochemical course of several biochemical transformations have been analyzed.
A methyl group may rotate around the R—C axis. This is a free rotation only in the simplest cases like gaseous CClH 3. For the model case of C 2 H 6 this is discussed under the name ethane barrier. In condensed phases, neighbour molecules also contribute to the potential. Methyl group rotation can be experimentally studied using quasielastic neutron scattering.
Methyl is the IUPAC nomenclature of organic chemistry term for an alkane or alkyl molecule, using the prefix "meth-" to indicate the presence of a single carbon.

Like 2,4-pentanedione, ethyl acetoacetate exists predominantly in the enol form owing to stabilization by internal hydrogen bonding. Acetoacetic acid itself is unstable and loses carbon dioxide to give acetone:…. Although this process seems more complicated than the Dow process, it is advantageous because it produces two valuable industrial products: phenol and acetone.
