Decreasing order of acidic strength of different (-OH) group is:
Decreasing order of acidic strength of different (-OH) group is:
Open in App
Solution
The correct option is A w>x>y>z
w will be the most acidic, as the anion (formed after the proton is removed) is stabilized by resonance in benzene ring.
z will be the least acidic as the anion formed will experience a significant +I effect from the −CH2 group adjacent to it, thus destabilizing it.
x will be comparatively more acidic than y as it experiences less +I effect to a less extent. Hence the order of acidic strength is:
w>x>y>z
