Vedclass · Answer

(A) Mesityl oxide is an $\alpha,\beta-$unsaturated ketone with the structure $(CH_3)_2C=CHCOCH_3$. The longest carbon chain containing the ketone group has $5$ carbons. Numbering from the end closer to the ketone group gives the name $4-$Methylpent$-3-$en$-2-$one.Oxalic acid is the simplest dicarboxylic acid with the formula $(COOH)_2$. Its $IUPAC$ name is Ethanedioic acid.Therefore,the correct $IUPAC$ names are $4-$Methylpent$-3-$en$-2-$one and Ethanedioic acid.

$IUPAC$ names of mesityl oxide and oxalic acid are respectively
