Question

Correct IPUAC name of the following compound is?

Answer 1

Priority order: Carboxylic acid $>$ aldehyde $>$ amine

Numbering the carbon chain accordingly:

$CHO$ $N{H}_2$

$HOO\underset{1}{C}-\stackrel{|}{\underset{2}{C}H}-\stackrel{|}{\underset{3}{C}H}-\underset{4}{C}OOH$

The substituents are formyl group at $C-2$ & amino group at $C-3$ .

Hence the IUPAC name is $2-formyl-3-amino-butan-1,4-dioic$ $acid$ .
