Ethers are a class of compound of the general formula R-O-R’ R and R’ can be alkyl or aryl Structure Ethers can be thought of as alkyl analogues of water Uses Since ethers are relatively unreactive and are strongly polar (due to the lone pairs on the oxygen) they are commonly used as solvents for organic reactions |

What is the nomenclature of an ether?
- The nomenclature of ethers rotates around two standard ways of naming, which are given below. The common ether nomenclature follows the rule of naming different alkyl/aryl groups that are attached in alphabetical order to the oxygen atom on either side and adding the word ether to it finally.
What is the general formula of an ether?
- The general formula of ether is given as R-O-R, R-O-R’, R-O-Ar or Ar-O-Ar where R represents an alkyl group and Ar represents an aryl group. We generally come across this topic in organic chemistry and it is also a widely covered topic in biochemistry where we find common linkages between carbohydrates and lignin.
What are the steps in naming ethers?
- Ethers can be named by naming each of the two carbon groups as a separate word followed by a space and the word ether. The -OR group can also be named as a substituent using the group name, alkox CH 3 -CH 2 -O-CH 3 is called ethyl methyl ether or methoxyethane. The smaller, shorter alkyl group becomes the alkoxy substituent.
What is the difference between alcohols and ethers?
- Ethers have a similar structure to that of alcohol, whereas both Ethers and Alcohols have a similar structure to that of water. One hydrogen atom of a molecule of water is replaced by an alkyl group in alcohol, whereas coming to the ether, both the hydrogen atoms are replaced either by alkyl or aryl groups.
