WebDec 10, 2024 · Consequently, an ether has about the same solubility in water as the alcohol that is isomeric with it. For example, dimethyl ether and ethanol (both having the molecular formula C 2 H 6 O) are completely soluble in water, whereas diethyl ether and 1-butanol (both C 4 H 10 O) are barely soluble in water (8 g/100 mL of water). WebIts chemical formula is F− (CF (CF 3 )−CF 2 −O) n −CF 2 CF 3. The ether groups are integral to the polymer chain.
