Vedclass · Answer

(A) According to the $IUPAC$ priority rules for functional groups,the order of priority is: $-COOH > -SO_3H > -COOR > -COX > -CONH_2 > -CN > -CHO > -CO- > -OH > -NH_2 > -OR$. Comparing the given groups: $1$. Carboxylic acid $(-COOH)$ $2$. Sulphonic acid $(-SO_3H)$ $3$. Amide $(-CONH_2)$ $4$. Aldehyde $(-CHO)$ Thus,the correct decreasing order is $-COOH > -SO_3H > -CONH_2 > -CHO$.
