Ether Compounds
An ether is the product of the substitution of hydrogen in the hydroxyl group of an alcohol or phenol by a hydrocarbon group, with the general formula R-O-R', R and R' being either the same or different. An ether in which the two are the same is called a symmetric ether, also called a simple ether or a mono ether; an ether in which the two are not the same is called an asymmetric ether, also called a mixed ether or a hybrid ether. If R and R' are carbon atoms at the ends of an organic group, they are called cyclic ethers, such as ethylene oxide. Most ethers are colorless liquids at room temperature, have an aroma, a low boiling point, are lighter than water, and are stable in nature. Ethers generally have anesthetic effects, such as ether is a commonly used clinical inhalation anesthetic.

Structure and Chemical Bonding of Ethers
The general structural formula of ether is R-O-R(R'), Ar-O-R or Ar-O-Ar(Ar') (R=hydrocarbon group, Ar=aromatic group). The bond angle of the ether is about 110°, the C-O bond length is 140 pm, and the rotational energy barrier of the C-O bond has a small energy, while the bonding ability of water, alcohols and oxygen in the ether molecule is similar. According to the valence bond theory, the hybridization state of the oxygen atom is sp3.
Oxygen atoms are more electronegative than carbon, so the α-hydrogen atom connected to oxygen is more acidic than the carbon connected α-hydrogen atom, however it is less acidic than the carbonyl α-hydrogen atom.
Nomenclature of Ethers
The common nomenclature of ether is to add the word "ether" after the hydrocarbon group, and the word "two" can be omitted in the customary symmetrical ether. The order of the two different groups of the ether is usually: the first small group after the large group. The naming convention for aromatic ethers is: phenyl or aromatic hydrocarbon group first. In English, the naming is in alphabetical order. Crown ethers are named x-crown-y, with x representing the total number of atoms in the ring and y representing the number of oxygen atoms in the ring.
Classification of Ethers
Ethers in which the two hydrocarbon groups are the same are called symmetric ethers, also called simple ethers or mono ethers. Ethers in which the two hydrocarbon groups are not identical are called asymmetric ethers, also called mixed ethers or hybrid ethers.
Based on the category of the two hydrocarbon groups, ethers can also be categorized as fatty ethers and aromatic ethers.
Among fatty ethers, ethers in which the molecule is not composed of oxygen and carbon atoms bonded into a cyclic ether structure are called acyclic ethers, and can also be subdivided into saturated ethers and unsaturated ethers. Ethers in which oxygen and carbon atoms are combined to form a cyclic ether structure are called cyclic ethers. Ethers containing oxygen on the ring are called internal ethers or epoxides. Macrocyclic ethers containing more than one oxygen are called crown ethers because of their crown-like shape.
