1.	How does benzoic acid reacts with (1)PCL5 (2) mixture of conc. HNO3 and conc.H2SO4
Answer» (1) PCl₅ With phosphorus pentachloride (PCl₅) or thionyl chloride (SOCl₂), benzoic acid reacts to form benzoyl chloride (C₆H₅COCl), which is classified as an acid (or acyl) halide. (2) mixture of conc. HNO₃ and H₂SO₄ Benzoic acid reacts with concentrated nitric acid (HNO₃), in the presence of sulfuric acid as catalyst, leading to nitration of the ring. Reaction of benzoic acid with fuming sulfuric acid (H₂SO₄) leads to sulfonation of the aromatic ring, in which the functional group SO₃H replaces a hydrogen atom on the aromatic ring.

Answer»

(1) PCl₅

With phosphorus pentachloride (PCl₅) or thionyl chloride (SOCl₂), benzoic acid reacts to form benzoyl chloride (C₆H₅COCl), which is classified as an acid (or acyl) halide.

(2) mixture of conc. HNO₃ and H₂SO₄

Benzoic acid reacts with concentrated nitric acid (HNO₃), in the presence of sulfuric acid as catalyst, leading to nitration of the ring.

Reaction of benzoic acid with fuming sulfuric acid (H₂SO₄) leads to sulfonation of the aromatic ring, in which the functional group SO₃H replaces a hydrogen atom on the aromatic ring.
