Question

What is the IUPAC name of the compound ?

Answer 1

Here the longest chain of the compound containing principal 2 functional groups `-COOH` has total `7` C-atoms.
So stem name is 'hept'

and the compound is saturated one .

So next suffix added with it is 'ane'

After that suffix for two `-COOH` groups i.e . 'dioicacid' is added.

The only substituent carboxymethyl `(-CH_2COOH)` group is linked with the main chain at position `C_4`. So this name is to be added as prefix with locant `4` before it

Hence the IUPAC Name becomes

`color(red)(4-"carboxymetylheptanedioicacid")`
