MCQ
The order of acidity for the following compounds is:
- AI > II > III > IV
- BIII > I > II > IV
- CI > IV > II > III
- DI > III > IV > II
✓
Answer
- I > IV > II > III
Explanation:
COOH and OH group are electron-withdrawing groups. COOH is the main group here because of its high acidic nature.
OH group actively withdraws electron density from ortho and para positions greater than at meta position.
Ortho position withdraws less electron density than para position because of ortho effect. More the number of OH groups, more will be the withdrawing capacity and more will be the acidity.
