Why does ethanol have a higher boiling point than dimethyl ether?

The OH group in ethanol is highly hydrogen bonded which requires much more heat energy to break before boiling can occur. Dimethyl ether, which has the same molecular formula and molecular weight does not have this due to the ether linkage.

What is dme a fuel?

Dimethyl ether (DME) is the organic compound with the formula CH3OCH3. The simplest ether, it is a colourless gas that is a useful precursor to other organic compounds and an aerosol propellant. Dimethyl ether is also promising as a clean-burning hydrocarbon fuel.


When one molecule of dimethyl ether is burned how many molecules of product are formed?

One molecule of dimethyl ether will yield five molecules of product when burned, two carbon dioxide and three water.


Do structural isomers have the same physical properties?

No. For example, ethanol (CH3CH2OH) and dimethyl ether (CH3OCH3) are structural isomers but have different boiling points. (The boiling point of ethanol is much higher than the boiling point of dimethyl ether because ethanol molecules can form hydrogen bonds with each other while dimethyl ether molecules cannot.)

Is dimethyl ether polar or nonpolar?

DME (DiMethyl Ether) is rather unpolar because it is symmetrical (+-+), it has a bended or hooked (V-like) structure (about 120o corner) with 'longer, more spread legs' than water (104.5o). It is more polar than di-Ethyl ether however.


Is ethanol a structural isomer?
