What are \(X,\;Y,\;Z\) respectively in the following reaction sequence?

• A. 1
• B. 2
• C. 3
• D. 4

Hint:

An aryl halide containing a \(\mathrm{-NO_2}\) group at the ortho or para position undergoes nucleophilic substitution with aqueous \(\mathrm{NaOH}\) much more readily. \[ \boxed{ p\text{-Nitrochlorobenzene} \xrightarrow[\mathrm{H^+}]{\mathrm{NaOH},\,443\,K} p\text{-Nitrophenol} } \]

Answer 1

The Correct Option is A
