Reaction of Halogen with Carboxylic Acids:
When a halogen reacts with carboxylic acids, it undergoes a substitution reaction to form an acyl halide. This reaction is known as the Hell-Volhard-Zelinsky reaction.
Explanation:
- In the Hell-Volhard-Zelinsky reaction, a carboxylic acid is treated with a halogen such as chlorine, bromine, or iodine in the presence of a small amount of phosphorus to form the corresponding acyl halide.
- The reaction proceeds via a free radical mechanism, where the halogen radical abstracts a hydrogen atom from the α-position of the carboxylic acid, forming a hydrogen halide and an acyl radical.
- The acyl radical then reacts with the halogen to form the acyl halide product.
- This reaction is useful for the conversion of carboxylic acids to acyl halides, which are important intermediates in organic synthesis.
- The Hell-Volhard-Zelinsky reaction is particularly useful for the preparation of α-halogenated carboxylic acids, which are versatile building blocks in organic chemistry.
- Overall, the reaction of halogen with carboxylic acids in the Hell-Volhard-Zelinsky reaction allows for the efficient synthesis of acyl halides, providing valuable compounds for further transformations in organic synthesis.
Therefore, the correct answer to the given question is option 'B' carboxylic acids.
