Diethyl ether is the simplest ether, is a colorless, volatile, flammable liquid with a characteristic odor. 

Structure

Diethyl ether is consisting of two ethyl groups-C2H5-bonded to one oxygen atom. The structure of diethyl ether is C2H5-O-C2H5. The carbon-oxygen double bond is strong and the molecule is nonpolar.

The two carbon atoms in the molecule are linked by an oxygen atom, forming a three-membered ring. 

Is Diethyl Ether Polar?

Diethyl ether is a polar molecule. This means that one side of the molecule has a positive electrical charge, while the other side has a negative charge. The polarity of the molecule arises from its structure. Ether is composed of two ethyl groups (C2H5) attached to an oxygen atom (O). Each of the ethyl groups has a slightly negative charge due to the presence of two hydrogen atoms. On the other hand, the oxygen atom has a slightly positive charge due to the extra electron it has. This unequal distribution of charges causes a dipole moment in the molecule, making it polar.
