Choose from the indicated protons, the one that is most acidic
Options
- A1
- B2
- C3
- D4
Correct answer
D. 4
Step-by-step solution
Deprotonation of hydrogen labelled 4 produces a conjugate base which has more stable resonating structure and a resonance structure in which negative charge is present on the electronegative oxygen atom. Therefore, hydrogen labelled 4 is most acidic.
