International Union of Pure and Applied Chemistry that is also known as IUPAC. It is used for naming of various chemical compounds.
Ethers are chemical compounds which contain the functional group "-O-". For example, R-O-R' is an ether where R and R' can be same or different alkyl or aryl groups.
Alkoxy substituent is named first in the ether and the complex group is provided with the root name and it is named later on.
(a) The given chemical compound is as follows.
According to the numbering, a methyl group is present at position-1 on moving from left to right. On the other hand, four carbon atoms are linearly present on the right side of oxygen atom.
Hence, a suffix "butane" will be added in its naming.
Therefore, name of this compound is 1-methoxybutane.
(b) The given compound is as follows.
On the left side of oxygen atom, two carbon atoms are attached. Hence, a prefix ethoxy will be in the naming of this compound as "-oxy" is for the oxygen atom present in this ether.
On the right side of oxygen atom three carbon atoms are linearly attached to each other. So, prefix propane will be added to its name.
Therefore, name of this compound is 1-ethoxypropane.
