What structure corresponds to methyl propyl ether?

Methyl propyl ether is an ether that consists of a methyl group (–CH₃) attached to an oxygen atom, which is also attached to a propyl group (–CH₂–CH₂–CH₃). The structure must therefore represent an ether composed of these two alkyl groups linked by an oxygen atom.

The correct structure accurately illustrates this by having the methyl group on one side of the oxygen atom and the propyl group on the other side. This arrangement directly aligns with the definition of an ether, where two hydrocarbon chains are connected by an oxygen atom.

In the other options, the structural arrangements do not properly correspond to the definition of methyl propyl ether. For instance, components in some options either have additional functional groups or different hydrocarbon frameworks, which makes them distinct from the simple ether characterized by a methyl and a propyl group linked through an ether bond. Thus, the selected answer embodies the fundamental structure of methyl propyl ether without deviations or additional functional groups.
