Current Question (ID: 10852)

Question:

$\text{Incorrectly matched common name with IUPAC name is-}$

Options:

1. $\text{Benzalacetophenone - (E)-1,3-Diphenylprop-2-en-1-one}$
2. $\text{Glutaric acid - Pentenedioic acid}$ (Correct)
3. $\text{Adipic acid - Hexane-1,6-dioic acid}$
4. $\text{Pyruvic acid - 2-Oxopropanoic acid}$

Solution:

$\text{Hint: Follow the IUPAC name of some common compounds.}$ $\text{The correct name of glutaric acid is Pentanedioic acid, not pentenedioic acid. The structure of glutaric acid is as follows:}$ $\text{HOOC-CH}_2\text{-CH}_2\text{-COOH}$ $\text{The structure of other compounds are as follows:}$ $\text{Pyruvic acid, hexane-1,6-dioic acid, and (E)-1,3-diphenylprop-2-en-1-one respectively.}$ $\text{Glutaric acid is a 5-carbon dicarboxylic acid, so its IUPAC name should be pentanedioic acid (from pentane), not pentenedioic acid (which would suggest a double bond).}$
