Vedclass · Answer

(B) The formation of a white precipitate with silver nitrate $(AgNO_3)$ after treatment with $NaOH$ indicates the presence of chloride ions $(Cl^-)$ in the solution.$C_6H_5CH_2Cl$ is a primary benzylic halide. It undergoes nucleophilic substitution with aqueous $NaOH$ to form benzyl alcohol and $NaCl$.$C_6H_5CH_2Cl + NaOH_{(aq)} ightarrow C_6H_5CH_2OH + NaCl$When $dil. HNO_3$ and $AgNO_3$ are added to the resulting solution,the $Cl^-$ ions react with $Ag^+$ to form a white precipitate of $AgCl$.$Ag^+ + Cl^- ightarrow AgCl_{(s)} 	ext{ (white ppt)}$$C_6H_5Cl$ (chlorobenzene) does not undergo nucleophilic substitution under these mild conditions,and $C_6H_4(CH_3)Br$ would yield a yellow precipitate of $AgBr$.

An organic halide is shaken with aqueous $NaOH$,followed by the addition of $dil. HNO_3$ and silver nitrate solution,which gives a white precipitate. The substance can be:
