Question

The $IUPAC$ name of succinic acid is:

• A. $1,4\text{-Butanedioic acid}$
• B. $\text{Dimethyl-2-acid}$
• C. $1,2\text{-dimethyldoic acid}$
• D. $\text{None of these}$

Answer 1

The correct option is A $1,4\text{-Butanedioic acid}$

Structure of succinic acid is $HOOC-C{H}_2-C{H}_2-COOH$. It is a dicarboxylic acid. Suffix for carboxylic acid is "oic acid". The $IUPAC$ name of succinic acid is $1,4\text{-Butanedioic acid}$.

$\stackrel{1}{C}OOH-\stackrel{2}{C}{H}_2-\stackrel{3}{C}{H}_2-\stackrel{4}{C}OOH$

Common name of few dicarboxylic acid.
$\text{Oxalic acid}\to (COOH{)}_2$
$\text{Malonic acid}\to COOH\left(C{H}_2\right)COOH$
$\text{Succinic acid}\to COOH(C{H}_2{)}_{2}COOH$
$\text{Glutaric acide}\to COOH(C{H}_2{)}_{3}COOH$
$\text{Adipic acid}\to COOH(C{H}_2{)}_{4}COOH$
$\text{Pimelic acid}\to COOH(C{H}_2{)}_{5}COOH$
