Question:
The correct order of their acidic strength for the given compounds is:
The correct order of their acidic strength for the given compounds is:
Show Hint
Remember: $NO_2$ is a strong electron-withdrawing group, increasing acidity!

- IV > I > III > V
- IV > II > III > V
- III > II > V > I
- II > IV > III > V > I

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Concept
Acidity of substituted benzoic acids.
Step 2: Meaning
Electron-withdrawing groups increase acidity; electron-donating groups decrease it.
Step 3: Analysis
$NO_2$ (withdrawing) > $H$ > $CH_3$ (donating). Position also matters (ortho effect). The order follows the strength of these effects.
Step 4: Conclusion
IV > I > III > V is the correct order.
Final Answer: (A)
