Dimethyl ether is polar. It is more polar than an equivalent alkene but not nearly as polar as an ester or an amide.
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.
methanol dehydration to dimethyl ether (DME). it is simple
Dimethyl ether is CH3-O-CH3
dimethyl ether
The oxygen in the dimethyl ether gives it more polarity than pentane; thus making it soluble in water

S(CH3)2 is the formula for Dimethyl Sulfide analogous to Dimethyl ether
Petroleum and ether are NOT polar. Salt is polar.

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