derivatives of second order

The IUPAC names of open chain aliphatic aldehydes and ketones are derived from the names of the corresponding alkanes by replacing the ending -e with -al and -one respectively. The following steps are followed: a) The longest carbon chain containing the carbonyl carbon is taken to deci..

: alkoxy Ethers are alkoxy derivatives of alkanes. These are represented by the general formula R-O-R', where R and R' are alkyl groups. Ether is termed as simple ether when R and R' are the same. If the two alkyl groups (R and R') are different, the ether is termed as a mixed ether. W..

Nomenclature of Ethers - Common names of ethers follow after the names of alkyl / aryl groups written as separate words in alphabetical order. The word ether is added at the end. In case of simple ethers, the prefix di is attached before the name of the alkyl group. Examples: C 2..
