Which of the following is the strongest carboxylic acid? (2022)

Step 1: Understand what a carboxylic acid is. It is a type of organic compound that contains a carboxyl group (-COOH).
Step 2: Identify the options given in the question. We need to compare the acidity of these carboxylic acids.
Step 3: Recall that the strength of a carboxylic acid is determined by how easily it can donate a proton (H+).
Step 4: Recognize that formic acid (HCOOH) has a hydrogen atom directly attached to the carbonyl carbon (C=O).
Step 5: Understand that this hydrogen atom increases the acidity of formic acid compared to other carboxylic acids that may have larger or more complex structures.
Step 6: Conclude that formic acid is the strongest carboxylic acid among the options because of its structure.
