Question

The Correct IUPAC name of the following compound is $HOOC-C{H}_2-\underset{OH}{\underset{|}{\stackrel{COOH}{\stackrel{|}{C}}}}-C{H}_2-COOH$

• A. 3 - Carboxy - 3- hydroxypentane - 1, 5 - dioic acid
• B. 3 - Carboxy - 3- hydroxypentane - 1, 5 - dioic acid
• C. 2 - hydroxy propane -1, 2, 3 tri carboxylic acid
• D. 2 -carboxymethyl - 2 - hydroxybutanedioic acid

Answer 1

The correct option is C

2 - hydroxy propane -1, 2, 3 tri carboxylic acid

When there are more similar chain terminates groups (like$-COOH$,$-CHO$,$-CN$)are present all the groups are considered as substituents of parent chain.

$HOOC-\stackrel{1}{C}{H}_2-\underset{OH}{\underset{|}{\stackrel{COOH}{\stackrel{|}{\stackrel{2}{C}}}}}-\stackrel{3}{C}{H}_2-COOH$
