Ethers

They are organic compounds in which oxygen is bonded to two carbon groups, alkyl groups.

Functional group:                    R-O-R

Physical properties:
 - Ethers have no H atoms bond to the O atom as in alcohols.
 - Therefore molecules in the pure liquid are incapable of hydrogen bonding.
 - Ethers have similar boiling points to alkanes of comparable molecular weigth.
 - Not soluble in water.

Chemical properties:
 - Ethers are flammable.
