Question

In the following reaction, X, Y and Z are

(a) X = CH₃Cl; Y = Anhydrous AlCl₃; Z = HNO₃ + H₂SO₄

(b) X = CH₃COCl; Y = Anhydrous AlCl₃; Z = HNO₃ + H₂SO₄

(c) X = CH₃Cl; Y = Conc. H₂SO₄; Z = HNO₃ + H₂SO₄

(d) X = CH₃Cl; Y = Dil. H₂SO₄; Z = HNO₃

Answer 1

Answer is : (a) X = CH₃Cl; Y = Anhydrous AlCl₃; Z = HNO₃ + H₂SO₄

For the given reaction,

When benzene reacts with CH₃Cl in presence of anhyd.AlCl₃, then toluene is formed. This reaction is known as Friedel-Craft’s reaction. The formed toluene then undergoes nitration to give 2-nitrotoluene.
