Question

Correct IUPAC name of following compound is :

$HOOC-CH\left(CHO\right)-CH\left(N{H}_2\right)-COOH$

• A. $2$-Amino-$3$-formyl butane-$1,4$-dioic acid
• B. $2$-formyl-$2$-amino butane-$1,4$-dioic acid
• C. $3$-amino-$2,2$-formylbutane-$1,4$-dioic acid
• D. $2$-amino-$3$-carboxy-$4$-oxobutanoic acid

Answer 1

The correct option is A $2$-Amino-$3$-formyl butane-$1,4$-dioic acid

Correct IUPAC name of the compound $HOOC-CH\left(CHO\right)-CH\left(N{H}_2\right)-COOH$ is $2$-amino-$3$-formylbutane-$1,4$-dioic acid.
The compound contains $4C$ atoms (including $2-COOH$) groups. Hence, it is a detivative of butane dioic acid. An amino group is present as a substituent on second $C$ atom and a forml group (aldehyde $-CHO$) is present on third $C$ atom. These substituents are named as perfixes in alphabetical order.
