What is Z in the following sequence of reactions? p -  chloronitrobenzene  → ( 2 ) H 3 O + ( 1 ) NaOH , 443   K X → 0 - 5 ° C ( ii ) NaNO 2 / HCl ( i ) Sn + HCl Y → 10 ° C H 2 O Z

Correct answer

2

Step-by-step solution

Aromatic amine reacts with nitrous acid and mineral acid to form diazonium salt and produces water as a side product. This reaction is known as Diazotization Reaction. On hydrolysis of Benzene diazonium chloride, Nitrogen molecules escape as nitrogen gas. The OH group of water attacks the vacant site left after removal of nitrogen gas. This results in the formation of phenol. Also, Small amount of NaCl is also generated.
