Vedclass · Answer

(D) For reaction $(a)$: Benzoic acid contains a $-COOH$ group,which is a deactivating and meta-directing group. Nitration with $Conc. HNO_3 + Conc. H_2SO_4$ yields $m$-nitrobenzoic acid as the major product. Thus,$X$ is $3$-nitrobenzoic acid.For reaction $(b)$: This is the Hell-Volhard-Zelinsky $(HVZ)$ reaction. Carboxylic acids having an $\alpha$-hydrogen atom are halogenated at the $\alpha$-position on treatment with $Br_2$ in the presence of small amount of red phosphorus. The product $Y$ is an $\alpha$-bromo carboxylic acid,$R-CH(Br)-COOH$.

What are $X$ and $Y$ in the following reactions?
a) Benzoic acid $\xrightarrow[Conc. H_2SO_4]{Conc. HNO_3} X$
b) $R-CH_2-COOH \xrightarrow[ii) H_2O]{i) Br_2 / Red \ P} Y$
