Question

Comparing (a) and (b), which of the following statements is correct?

• A. (b) is more acidic than (a)
• B. Conjugate base of (b) is stabilised by hydrogen bonding
• C. (a) is more acidic than (b)
• D. None of the above

Answer 1

The correct option is C (a) is more acidic than (b)

Comparing (a) and (b):
The conjugate base of A is more stable as compared to the conjugate base of B since H-bonding stabilises the anion in the former one.

Compound (b) does not form H-bonding so it is least acidic compare to (a).

Hence, statement (c) is correct.
