Vedclass · Answer

(A) In the $IUPAC$ system of nomenclature,the priority order for functional groups is determined by specific rules. According to the $IUPAC$ priority table,the carboxylic acid group $(-COOH)$ has the highest priority among the given groups. The sulfonic acid group $(-SO_3H)$ follows,then the amide group $(-CONH_2)$,and finally the aldehyde group $(-CHO)$. Therefore,the correct decreasing order is: $-COOH > -SO_3H > -CONH_2 > -CHO$.

The correct decreasing order of priority for the functional groups of organic compounds in the $IUPAC$ system of nomenclature is:
