Chemistry · Carboxylic Acids and its Derivatives

The reaction of a carboxylic acid (acetic acid in this case) and PCl₅ produces an acyl chloride (CH₃COCl in this case) along with POCl₃ and HCl.

The reaction of a carboxylic acid (acetic acid in this case) and PCl₅ produces an acyl chloride (CH₃COCl in this case) along with POCl₃ and HCl. 

Option B is incorrect because it suggests the formation of an incorrect product, CH₃COCl, and does not correctly account for the products of the reaction. 

Option C is incorrect as it suggests the formation of CH₃Cl, which is not a product of the given reaction between acetic acid (CH₃COOH) and phosphorus pentachloride (PCl₅). 

Option D is incorrect because it proposes the formation of H₂, which is not a product of the reaction between CH₃COOH and PCl₅. The reaction primarily involves the substitution of hydroxyl (-OH) groups in acetic acid with chlorine atoms from PCl₅.
