Question

What is the IUPAC name of the given compound?

Answer 1

Chemical compounds are of different types. These are classified based on the functional group present in these compounds. Esters are the compounds containing $- COOR$ where R is the alkyl group and this group is attached to another alkyl group. The compound is ester with two ester linkages and the IUPAC name is diethyl propanedioate.

Complete answer:
Based on the functional group present in chemical compounds, chemical compounds were classified into different types. Esters are one of the functional groups containing $- COOR$ group, where R is the alkyl group.
Esters contain a carboxyl part and alkoxy group. Given compound consists of a carboxyl part and an ethoxy group which reveals that the given compound is ester.
In the given compound there were two ethoxy groups and two carbonyl groups which were linked to the methylene group. Due to the presence of these two carbonyl groups the methylene group is very reactive and can be called an active methylene group.
The IUPAC name for ester group can be written as -oate. Due to the presence of two ethyl groups, the base chain is propane. Thus, the root word is propane.
The IUPAC name of the given compound is diethyl propanedioate.

Note:
The given compound is ester with two alkoxy groups. Here the alkoxy group is an ethoxy group. As there were two ester groups the suffix will be dioate. The common name of the given compound is malonic ester as it is derived from malonic acid. But, the common name and IUPAC name were different.
