Chlorobenzene (X) when reacted with reagent ‘A' gets converted to phenol (Y). The major product obtained from nitration of X gets converted to p-nitrophenol (Z) by reaction with reagent B. What are A and B respectively?
1
A = (i) NaOH, 623 K, 300 atm (ii) H; B = (i) NaOH, 443 K (ii) H+
2
A = (i) NaOH, 443 K (ii) H+; B = H2O, Δ
3
A= (i) NaOH, 323 K (ii) H+; B = (i) NaOH, 443 K (ii) H+
4
A = (i) NaOH, 623 K, 300 atm (ii) H+; B = H2O. A
