What is the most acidic compound among the following?
Understand the Problem
The question asks to identify the most acidic compound from a given set of compounds. This requires understanding the factors that influence acidity, such as electronegativity, resonance, inductive effects, and the stability of the conjugate base.
Answer
3,5-dinitrophenol is the most acidic compound due to the electron-withdrawing effects of the two nitro groups.
Based on the search results, the most acidic compound among those listed in the search snippets is 3,5-dinitrophenol. The presence of two nitro groups (-NO2) on the phenol ring increases the acidity due to their strong electron-withdrawing effect, which stabilizes the conjugate base after deprotonation.

Based on the search results, the most acidic compound among those listed in the search snippets is 3,5-dinitrophenol. The presence of two nitro groups (-NO2) on the phenol ring increases the acidity due to their strong electron-withdrawing effect, which stabilizes the conjugate base after deprotonation.
More Information
The acidity of a compound is determined by its ability to donate a proton (H+). Electron-withdrawing groups stabilize the resulting negative charge on the molecule after the proton is released, thus increasing acidity.
Tips
A common mistake is to only consider the presence of electron-withdrawing groups without considering their position and number.
