NEET Chemistry Reactions of Carboxylic Acids MCQ Question
Which of the following carboxylic acids has the strongest acidic strength based on its pK value? Consider the pK values: Hydrochloric acid (-7.0), Trifluoroacetic acid (0.23), Benzoic acid (4.19), and Acetic acid (4.76).
Trifluoroacetic acid (0.23)
Benzoic acid (4.19)
Acetic acid (4.76)
Hydrochloric acid (-7.0)
Correct Answer
Detailed Explanation
The strength of an acid is inversely related to its pK value. Lower pK values indicate stronger acids. Hydrochloric acid has the lowest pK value of -7.0, making it the strongest acid among the given options.
