# Which is more soluble in water CH3CH2OCH2CH3 or CH3CH2OCH3?

The methyl ether is SLIGHTLY more polar than diethyl ether....the methyl ether is MUCH more volatile...$\text{boiling point} = 7.4$ ""^@C...versus $34.6$ ""^@C...the major intermolecular interaction is dispersion force between the ether molecules.
But we have made a prediction, we should check the data for whether the prediction is true. Interestingly, $B {u}^{t} O M e$, has some considerable water solubility....
