Question

The reaction of $Q$ with $PhSNa$ yields an organic compound (major product) that gives positive Carius test on treatment with $N{a}_2{O}_2$ followed by addition of $BaC{l}_2$. The correct option(s) for $Q$ is/are:

• A.
• B.
• C.
• D.

Answer 1

Answer: (A), (D)

In option (b) and (c), $N{O}_2$ group (an EWG) is not present at ortho or para position w.r.t. the leaving group, so $ArSN2$ reaction will not be possible.
