Vedclass · Answer

(D) $1$. $FeCl_3$ test: Salicylic acid contains a phenolic $-OH$ group,which gives a violet color with neutral $FeCl_3$ solution. Benzoic acid does not contain a phenolic group and does not give this test.$2$. $Br_2$ water test: Salicylic acid undergoes electrophilic substitution with $Br_2$ water to form a white precipitate of $2,4,6-tribromophenol$ due to the activating effect of the $-OH$ group. Benzoic acid does not react with $Br_2$ water under these conditions.$3$. Therefore,both $FeCl_3$ solution and $Br_2$ water can be used to distinguish between them.
