Best Answer: ethanol because of the OH polar head is more soluble in water because it forms hydrogen bonds with H20 than the CH3 in dimethyl ether.Also alcohol is more soluble then ethers because of that OH polar head.In addition, 1-5 carbons chain are generally soluble but more preference is given to the one with less carbon chain and OH polar head.Source(s): took organic chem 1 and 2.ating Newest Oldest.

â¢ Petroleum is nonpolar and ether is relatively polar. â¢ Some ethers can be soluble in water, but petroleum ether is insoluble in water. â¢ Petroleum ether is highly flammable compared to ether. â¢ Ether can form hydrogen bonds with other molecules like water, but petroleum ether cannot do so.etroleum ether is a mixture of hydrocarbon compounds. This is a highly flammable and volatile liquid. The liquid is colorless. Petroleum ether is a nonpolar solvent. Though its name says ether, it doesnât have compounds with ether linkages. Petroleum ether is produced during the petroleum refining process.
