Vedclass · Answer

(C) The Carius test is used to detect the presence of halogens or sulfur in an organic compound. Treatment with $Na_2O_2$ oxidizes the sulfur to sulfate ions $(SO_4^{2-})$,which then form a white precipitate of $BaSO_4$ upon the addition of $BaCl_2$. For the product to give a positive Carius test,the organic compound must contain sulfur. In reaction $A$,$PhSNa$ acts as a nucleophile in an $S_NAr$ reaction,replacing the $F$ atom to form a product containing the $SPh$ group. Thus,the product contains sulfur. In reaction $D$,$PhSNa$ acts as a nucleophile in an $S_N2$ reaction,replacing the $Cl$ atom to form a product containing the $SPh$ group. Thus,the product contains sulfur. Both $A$ and $D$ yield products that contain sulfur,which will give a positive Carius test. Therefore,the correct options are $A$ and $D$.

The reaction of $Q$ with $PhSNa$ yields an organic compound (major product) that gives a positive Carius test on treatment with $Na_2O_2$ followed by the addition of $BaCl_2$. The correct option$(s)$ for $Q$ is (are):
