Vedclass · Answer

(B) Let us analyze each reaction:$(a)$ Malonic acid undergoes decarboxylation on heating to give acetic acid and $CO_2$. This is correct.$(b)$ Aniline forms a complex with $AlCl_3$ (a Lewis acid) due to the lone pair on nitrogen,which deactivates the ring and prevents Friedel-Crafts alkylation. The product shown is incorrect.$(c)$ Reimer-Tiemann reaction of phenol with $CHCl_3$ and $NaOH$ yields salicylaldehyde,not salicylic acid. This is incorrect.$(d)$ Acetaldehyde reacts with sodium bisulfite to form a bisulfite addition product. This is correct.$(e)$ Gattermann-Koch reaction of benzene with $CO$ and $HCl$ in the presence of anhydrous $AlCl_3/CuCl$ gives benzaldehyde. This is correct.Thus,reactions $(b)$ and $(c)$ are incorrect.
