Vedclass · Accepted Answer

$o$-Hydroxybenzoic acid

Vedclass · Answer

(A) The reaction sequence is as follows:$1$. When $o$-hydroxybenzoic acid (salicylic acid) is heated with $Zn$ dust,the $-OH$ group is reduced to $H$,yielding benzoic acid.$2$. When $o$-hydroxybenzoic acid is heated with soda lime $(NaOH + CaO)$,decarboxylation occurs,removing the $-COOH$ group and yielding phenol.Therefore,the compound $X$ is $o$-hydroxybenzoic acid.

An aromatic compound $X$ when heated with $Zn$ powder gives benzoic acid,but when heated with soda lime,it gives phenol. Identify the compound $X$.
